Such a great experience here. We were in and out the door in a few hours with the sale completely done, and the car was ready 2 days later! Mike Foster was so pleasant to work with, and explained everything in the car to us in detail. Highly recommend, and the GMC Yukon XL Denali we brought home!

Get place to buy car. I worked with Brian Mahah. Great guy knows his product.you cant go wrong.

I emailed Mike regarding locating a 2015 GMC Canyon. I informed him where it could be located. We went in and made a deal fairly quickly on a handshake. It was all done without any fuss or muss and, especially, no dealer BS. Mike, a low-key guy for a car salesman, was as good as his word. There was even movement on the price of this hot-selling truck. Due to the extreme Massachusetts weather and having the bed sprayed (which Colonial took care of) it took about a week and a half to pick up. Also, the dealer that I had located with the exact truck I wanted had traded it to a dealer in another state. Mike bird-dogged it down for me without my ever knowing it. The entire process, including the financing, was done politely and professionally. I wouldnt hesitate to buy another vehicle from Colonial. I havent needed the service department yet but I look forward to the same type of service that Mike gave me. If all GM dealers were as good as Colonial GMC, GM wouldnt have had the problems it did.

I went to you guys for an oil change and a full car inspection to make sure everything was fine with the car. I am going on a big trip and I wanted to make sure the car did not need anything to get fix. My car has 120k miles so been sure is always good. After picking my car up I realized you guys did not do a full check up. Before I left the car at the dealership I check for all fluids (coolant, wipers fluids, wipers) and all of them need it fill up and blades need it to be change since they are so old, tire pressure was also not done. 2 tires needed air and they were still the same when I pick the up the car. Tired rotation was not done either. None of this things were done and because of it I felt like I was taking advantage of and my car was not check! I paid $125 dollars and received nothing in return besides a simple oil change! I told the guy in the morning that I was going on a big trip and I need it my car 100 secure. Check tires, wheel balance and alignment fluids etc and I am really angry and disappointed I did not get anything done. I felt so unsafe I decided to rent a car instead. I go to the dealership because I want to make sure everything goes well and pay high prices to ensure safety. I could have gone to a regular car shop for half the price and a better service

Our company recently purchased a great truck from Colonial GMC. Mike Foster worked diligently to find us the perfect vehicle for our needs. In fact, he even had a truck brought in from a different location for our purchase. Mike made the process very simple and the dealer delivered an exceptionally clean & detailed used vehicle. I consistently get comments about how the truck appears brand new despite being a 2011.Our company will continue to do business with Colonial GMC and Mike Foster in the future. It was a great experience from start to finish.

The initial greeting was great, the service was more than expected and exceeded expectation. The only adjustment I would make is closing the time gap on your throughput to give customers a better and shorter experience. It seems as though something in communication is off on that front in regards to average capacity and accommodation to fitting that capacity. I should not have to sit at a dealership for 5 hours when I can take 2 hours to change the same brakes and rotors myself.

Steve Smith was the sales associate that assisted me with my purchase. He was patient and was a great help through the process. Steve answered any questions I had to my satisfaction. The entire team there were cordial and helpful. Sam and Richard are two other people I interacted with. I speak highly of them also. I would definitely consider purchasing from this dealership again.

My car died on the Mass Pike (100 miles away from home!) and I was towed to Colonial because I own a GMC. As it turns out the Water Pump blew. Steve and Anthony were fantastic. They were able to fix my car on the spot and have me on my way in just a few hours.If I lived in the area, I would definitely go there again.

I had a unique problem with the failing roof on my brand new Cascada convertible. I was stuck under a bridge for over two hours in the rain because the roof would not go up. Colonial kept the car until they could finally get to fix it and gave me a loaner. With service like this,I will buy from Colonial forever

This was an excellent car buying experience! Mike Foster, our salesman, found exactly the car I wanted. No nonsense, no compromises!Richard, who tales care of the financial transactions, came up with a very satisfactory lease. It was in line with the prices that had been advertised in the Globe.For an honest, easy car buying experience, this is the place to go. And ask for Mike!

We had quite the ordeal with our 2014 Buick Regal. After driving back from Connecticut, the engine suddenly lost power and the car stalled and shut off. After waiting over 4 hours for triple A we finally got the car towed to your shop. Needless to say, I wasnt in the greatest mood the next morning. This is where the story gets better. The people at the dealership, and especially Anthony in the service department took care of everything smoothly. He was prompt with letting us know the timeframe for the repairs, took care of getting us a rental care and really turned the ordeal into a pleasant experience. He got the car fixed sooner than expected and its been running great. I especially appreciate him taking the time to explain the problem, how they were going to fix it and the issues that might come up, this transparency is really something you dont receive very often anymore.Im extremely happy with the service they provided and the overall level of professionalism and courtesy Anthony showed us. The only minor complaint I have was that the car was pretty much completely covered in bird excrement when we picked it up, a quick wash would have been appreciated but is really not a big deal.Thanks again for all the help and we know where were coming if we ever need service again.

What a great Dealership to get a car from! This was my first time purchasing a car and everyone at the dealership was super helpful and not pushy at all. I worked with Mike Foster, Steve and Dick and had a wonderful experience at Colonial. 10/10 Would recommend!!

After careful research, I purchased a used car at Colonial Buick, GMC. I knew beforehand exactly what model I wanted, what mileage and condition, and what price range. The car was listed at an excellent price, several thousand dollars below comparable cars in the area. It had a scrape on the bumper which occurred during snow removal operations. Colonial sent it to an authorized Mercedes shop for a flawless repair.The sales staff is courteous and helpful, the service is prompt and thorough. I am a happy customer.

I have been taking my GMC Acadia here for service over the past six years. Much of the work was related to recalls, but Ive also had other repairs done. Anthony and Steve have always been helpful and I trust them for the most part. I always get exceptional service from Steve who I feel goes above the industry standard to work with me. He is good at communicating, giving me a competitive price for work and helps me with alternate transportation when my car needs service for more than one day. Do not work anyone other than Steve or Anthony.

Steve provided me with the best service! I recommend to bring your car there ALL times! Staff is super friendly and welcoming! I have had a great experience. If you go there look for Steve in the service dept. He will help you out with whatever you need.

Great experience. Called for an appointment to get my car looked at as the engine light was on. The service advisor, Tom was very friendly and explained all the details to me as I have never been to this location before having just recently moved into the area. He was extremely helpful throughout the entire process.

I had a great experience buying a vehicle from Colonial Buick GMC. Justin McDonald went beyond to assist us in obtaining a vehicle that my wife really loved. He even went as far as picking me up from my work place when I realized I would have been late to receive my vehicle. He was very professional and made sure all my concerns was addressed. I will highly recommend them to anyone because the buying process was easy and hassle free.

I recently was in the dealership to test drive a GMC Terrain I found online . I worked with Mike Foster to get information about purchasing the vehicle he was extremely nice and helpful! The dealership was very good about getting back to you with any questions and getting everything done in a quick and efficient manner! Highly recommend buying a vehicle here!

Anthony in Service at Colonial is THE BEST!!! I always ask for him directly, and he always takes care of me fast and efficiently. Anthony is always honest with me, and I really appreciate that. I bought my Terrain at Colonial; I get it serviced there; and, I will definitely get my next car from them. Great place, great attitudes!

Gabriel was a great salesperson. Very polite and eager to answer all of my questions. Sam was the Sales Manager who helped me find the right deal. I appreciate both men for making the process simple and fast. I love my new car!

A friend of mine is looking to lease or buy a GMC and I highly recommended Colonial. The staff here are extremely courteous and helpful. I have not had one complaint since going to them.I originally leased through another GMC dealership and it was a horror show once the papers were signed. I could not get in touch with anyone about services. When I called Colonial it was a different story. Nothing but smooth sailing!

Great experience all around. Justin was very informative and helpful, especially when narrowing down my selection for a new Canyon. The dealership owner made great efforts to ensure the process went smoothly. I am more than happy with the truck I purchased at Colonial Buick Pontiac GMC and highly recommend this dealership to others.

The team at Colonial Buick GMC of Watertown is genuinely the best. We went to 6 different dealerships (2 of them also other GMC dealerships). This group was super straight forward, presented the best deal, hands down, and were a super nice. Mike Foster and Richard Sterling were fantastic to work with. I called about 30 minutes before arriving and let them know my preferred make/model. By the time we arrived, the car was pulled up front and Mike was there to greet us. When we picked up the car later that week it was already registered, inspected, and worked out with our insurance. Highly suggest this team!

I just picked up my new truck from colonial. they could not have been more helpful in all aspects of the deal. every single person that I came in contact with was so nice. Steve Chavez was the salesman and really knew his stuff. I would go back there for my next purchase

Friendly staff, but wouldnt give me a callback when I believe they accidentally kept my registration, or when the engine code came back immediately. Also steep for visual inspection of other components (125ish per area), even when the car is already in for work. Be very careful what you ask them to look at unless you have $300 to burn.

I recently bought a new car from Brian Mahan. In my negotiations with both Brian and General Manager Paul Rowe, I was treated very fairly and courteously. It certainly was a pleasure to go through the details of our negotiations in a very straight forward process. I very highly recommend them both and Colonial Buick in general, especially the Service Department with Anthony.

Traded in my old Nissan Maxima for the newer one that Colonial had! Took a break from work just to go and take a look at it...and just a couple hours I was driving home in my new car! The guys there were super helpful and patient in getting me the car I wanted. Definitely happy with my purchase.

HIGHLY RECOMMEND!Brian Mahan is Top Notch!He is very knowledgeable and professional.Great communication! Great deal!Buying a car has never been so easy! Thanks Brian!My family will definitely be back and highly recommends Brian Mahan and Colonial GMC.

Purchased out GMC Terrain from this dealer. First interaction with Colonial. Zachary Waters was fantastic! New to this business he will fit right in. Made us feel welcome, comfortable and confident we were getting the best car at the right price. Would recommend highly.

From the time I walk in the door to the time I leave Im treated with such professionalism and Speedy attention. Everyone is friendly very courteous and attentive to what my needs are I love coming to Colonial to have my GMC service. YP GMC Arcadia owner

The entire process at Colonial was exceptional thanks to Brian Mahan. Hes a great guy, a straight shooter, and most important, an advocate for his clients.I felt like he wanted what was best for me the entire time and understood my needs throughout. Hes a genuinely good guy and made the buying experience very positive. I also had the easiest experience i the finance office Ive ever had and this is my 30th vehicle purchase.

Very happy. mike foster worked with me to get the truck i wanted within my budget. very laid back. no pressure. great experience. i would recommend mike and colonial to anyone looking for a gm vehicle.

I have a 2014 GMC Terrain which is still under warranty for oil change service. The representative (Steve?) who assisted me was a great guy and had me in and out in no time. He also gave my car a wash, which I definitely needed. Whenever I need another service for my car, I will be sure to go to Colonial.

I traded in my 2003 Yukon and purchased a 2015 Acadia Denali - I love it! I worked with Mike Foster, who was extremely personable and helpful throughout the entire process; he was readily available to assist me with anything I needed both during my search, and after my purchase. I would absolutely go through Colonial Buick GMC of Watertown again... the whole staff is very friendly, and based off of my experience with Mike, I would strongly recommend him to anyone who is in the market for a new car!! - Liz

Anthony and Steve were wonderful. My cars transmission unfortunately went at 77k, just about 2 months after the powertrain warranty was up - after reading many reviews I accepted the fact that GM may not cover it at all and that I would probably have to foot a very large bill. Anthony and Steve were able to get a large portion of it covered. I cant say that Ill buy another GM, but everyone in the service dept. here was great - over the past few years they never pressured me into getting unnecessary work done & were very accommodating. Thank you for your hard work!

Buying a new vehicle is the last thing I wanted to do. Then I met Mike Foster at Colonial Buick GMC. He didnt try to sell me something I didnt want, he didnt push me and tell me that he was giving me a special price because it was the end of the month. He didnt give me a time line to make a decision. Just helped me find what I was looking for and gave me a great price. What a fantastic experience. Really. Buying a car was a fast painless experience starting from an internet inquiry to getting my inspection sticker. Thanks!

2006 GMC Envoy for recall work. Made the appointment online and confirmed it the same way. Everything went smoothly from check in to check out. The personnel were very pleasant. Quite frankly, with having two local dealerships that I dealt with on this vehicle close, I was a bit apprehensive about dealerships in general. Nice surprise to find a good one. Worth the 40 minute drive to get there. Thank you.Janet Maggio

My wife and I went into Colonial GMC Buick with an idea on what we were interested in for a vehicle. Mike Foster was a great help in helping us find exactly what we were looking for. He helped us get into the perfect Acadia for us.

I wont buy a car anywhere else!!! I despise going car shopping especially because I typically have to being my two children with me (my husband works the night shift). I worked with Mike Foster who was super friendly and knowledgeable. I showed him a car I had found in his inventory that I wanted and even though that car had been sold he was able to locate me another car and honor the price. They have awesome deals for educators. I went back a few days later to see what my car was worth on a trade in and Mike asked if I wanted to take a new car home that day. I was not at all interested in spending my whole Saturday in a dealership but Mike had me out of there in no time at all. I was home in time to take my son to Dave and Busters (although in hind sight I think I would have rather stayed at the dealership) Great experience, Mike will see me again in three years for my next GMC Acadia

Bill Kutchar, (maybe wrong spelling of last name but this is what the lady at the desk gave me), did a wonderful job locating what was wrong with our Buick enclave. He was able to show us exactly what was wrong and explain that we had a blown fuse and after changing the fuse he took the extra step to see why it blew and found out that U-Haul wrapped the wire too tight when installing our hitch. we were extremely satisfied with his performance. He is a great mechanic.

We had a fantastic experience at Colonial Buick. Paul, Connor and Richard were all extremely accommodating. Highly recommend.

Went to test drive a vehicle which had been on the lot for a couple months and took it to my mechanic who found it needed an oil change, all new brakes, and had been in an accident. Pretty shady for a vehicle that (supposedly) had been through their 110 point inspection. Would have still purchased car, but no promise to take care of all the issues when confronted with this cars problems. Cant recommend this place.

Brian Mahan was very knowledgeable straightforward and did his best to help us. When the combination of features that we needed was not available after searching his computer he reviewed materials on the used cars we were considering, gave us great advice and sent us on our way.

I was looking for a pre-owned GMC Terrain, while looking online I came across one at this dealership. I sent them an email stating my interest in this vehicle and within 5 minutes a salesman Brian Mahan responded, he knew all about this vehicle and answered all my questions, he then made an appointment that afternoon for me to see and test drive. When I got there the vehicle was cleaned and parked right out front ready to go. When I returned from my drive I sat with Brian and he made my deal extremely easy he introduced me to the general mgr. who appraised my trade in, then it was off to finance to settle the details. I will picking up my vehicle in two days and I just wanted to share with the folks at the dealership and all what a great buying experience I had.

I had a wonderful experience at Colonial GMC in Watertown. From Brian in sales to Richard in finance to even the General Manager of the dealership Paul Rowe. They treated me with respect, handled all of my (very specific) needs, and got me into my new vehicle quickly and with no hassle. Thank you guys. I will purchase my next GMC at Colonial as well!

I wanted to buy car so I came. Didnt end up buying car but young chap who was showing car was respectable and great guy.

Didnt need to go in, the phone call was more than enough to avoid at all costs. Having someone that answers the phone with at least 10% receptiveness and 10% courtesy would be a plus.

We had excellent, honest, and speedy sales service at Watertown Buick. Brian was a pleasure to work with and followed through on all his promises. Were excited to be on Team Buick now. Ive been waiting to make the switch.

After doing intense research online on prices for GMC vehicles I came across Colonial GMC in Watertown, MA. They had the lowest prices and good inventory. I visited the dealership and sat down with Mike Foster. He made the new car buying experience very friendly and enjoyable. In no time we worked out a price and I bought the car. The next day I brought the car back for a wax detail touchup. The service representative took care of me right away. In no time flat I was out the door. I highly recommend this dealership. 5 stars!

If youve ever taken your GM vehicle anywhere else take it here and make your own decision. I was happy after trying many alternatives

I interacted with Mike Foster and he was very helpful right from the time of the first phone call to taking delivery of the vehicle. He made the experience very easy and worked with his business manager to expedite the process. He did not try to sell me stuff i dont need and overall the buying experience was a wonderful one. I will come back here if i ever need a buick/gmc again

I found the service department and sales staff at Colonial Buick to be professional and trustworthy. I have never been overcharged, and they have always honored their warranties. I recommend them highly.

I had a great experience at Colonial. Mike Foster was very knowledgable about the truck I was buying and he made the process easy. I highly reccomend Mike Foster and Colonial GMC Buick.

Recently, we were visiting Boston from Ohio to accompany our grandson for a consultation at Boston Childrens Hospital. Unexpectedly, the back door to our Enclave wouldnt open. We were closest to Colonial Buick GMC of Watertown and just stopped in unannounced. They immediately took us in, started working and corrected the problem. Anthony and all the service staff we met could not have been more professional, kind and generous with their time and expertise.We definitely give them our highest recommendation without reservation.

Brian made it easy for us to get into the new vehicle when our lease was up. I told him exactly what I was looking for and he did the work.

Brian Mahan is the best he went out of his way to help and to make sure it was pleasant buying experience

The true GMC repair shop that did work above & beyond my expectations, Colonial GMC service department repaired my vehicle and its been an uplifting experience for me talking with the service manager Anthony & the mechanic to continue all service needs at Colonial GMC

Great buying experience. Great price, great trade value compared to others and honest folks who were straightforward to deal with. Buy from here and Mike!

Wonderful service! Enjoy coming to get my oil changed.

Great people with no pressure and no hounding for you to buy a car and yes I got my truck 👍

Can not say enough about the staff,showroom to service,they won me over 4 years ago,love my Buick Encore

Worked with Mike Foster. Great service. Easy and fast transaction. In and out same day with my new car.

After looking into several different options I ended up purchasing a 2015 GMC Terrain. I dealt with Zachary Waters and he did a great job finding me the vehicle that I was looking for at the price I wanted to pay.

Super friendly and helpful. They respected me enough to be honest and realistic, thats more than i can say for other dealerships that try to screw you in any way possible. Buicks are awesome too but they sell themselves now a days.

I wanted to thank you and let you know how great service Tom Conlin provide and how much I enjoy coming to Colonial Buick GMC. I have a fleet company car and I travel a lot, I often need to fix issues.Tom is such an outstanding individual. He is so dedicated. He helped many times when I had to fix my GMC, and he make my life so much easier. He gave me his cell phone and for any issue or concern, I know that I can call or text him. For example yesterday the inspector at the inspection told me that I need to replace the tiers, I texted Tom and I know that I don’t need to worry about it. I will come soon and get all 4 tiered replaced.I have always been pleased with the Service Tom Conlin provide at Colonial Buick GMC. And I know that I will always come as long as Tom there.His professionalism and ability to get to everything done is highly appreciated. Such a commitment to great customer service is very rare.Thank you so much!

Working with Steven Santosuosso was a pleasure, very pleasant service consultant. He told us what had to be done and it was done in a timely manner. Did not give us the runaround was straight forward about the problem and the price that it would cost us .Overall we had a great experience at Colonial Buick GMC of Watertown .We will be back next time we need something done to our 2006 GMC Envoy . :0)Thanks so much for working with us Steve S.

I just had a very EASY car buying experience with Colonial GMC in Watertown. I worked with Paul and then ended up closing the deal with Brian Mahon in Sales and Dick in Finance. Being so busy, I cannot tell you how no pressure, speedy, and efficient they made the whole process. Such a refreshing change from most dealerships.

Just had a A+++++ experience buying my 2015 Denali HD from Mike Foster at Colonial…I wanted a specific truck and they went out of their way to find it and also gave me a great deal on it and my trade..I will be back soon for another truck…Excellent people to work with dont go anywhere else for a GMC..Thanks guys

Salesman - Mike Foster. Treaty me real well - very happy. Bought a Verano - Love it!

Sales Department is great. Mike Foster is great to deal with. No salesman games, up front and honest. a pleasure to business with. On the service side, you cant beat Steve Santosuosso, He is probably one of the nicest service people I have ever met. Fits you in if needed, answers your calls if you have questions, and he is very knowledgable. I will continue to do business with Colonial as long as these guys are there.

Honestly do not waste your time going here. Tom C was very unprofessional and just plain out rude. Too long of a story to tell but to make it short didn’t get my car fixed and PAID for “the service done”. If I could give 0 stars I would.

Outstanding experience (2nd!) with Brian Mahan of Colonial Buick GMC. I have purchased 2 vehicles and also used the service department. I highly recommend that you check this place out - give Brian a call and tell him that Paula referred you :) Happy Car Shopping!

Brian Mahan was terrific to work with when I had to find a new car for my son. We had only purchased cars in the past and I was interested in learning about GMCs leasing program. Brian was very patient with my questions and very clear with his responses. When it came down to appraising our trade-in, which was not a GMC car, Brian and his team at Colonial were very fair and competitive in their valuation. I discussed the monthly payment proposal with my son and he was concerned about not exceeding a payment he could assume once he is out of school. Brian found a model with the basic safety features I required but without any unnecessary costly upgrades. After driving home in my sons new Terrain, I started thinking that there might be one in my future as well!

Adam was extremely helpful and pleasant to work with. I would recommend anyone looking to purchase or lease a car contact Adam. He is a fair, laid back, and honest consultant.

I am extremely pleased with attention given when leasing my 2014 Verano.Justin McDonald is an excellent Sales Consultant.He has answered all my questions about the car. I appreciate all the staff at Colonial Buick for making leasing a great experience.

Brian Mahan was great - quick to respond to email and calls, and made the process of buying a new car very simple.

Mike did a wonderful, job from start to finish, getting us into the perfect GMC vehicle for us.

5 stars to an amazing dealership. it was a pleasure working with paul and connor. the buick envision is a vision.

Knowledgable employees go a long way. Brian sat me down and went through the options of multiple vehicals available. turns out what i was looking for was right on site. Still wrapped in plastic. The best fathers day present I couldve baught myself lol. He went through all the electronics, onstar, infotainment setup. Even setup the bluetooth on my phone for me. And the financing with Rich was a breeze. I left completely satisfied. Id definitely buy from him again. Thanks Brian for a pleasant experience.

I got GMC Terrain 2013 from this local dealer and the service is good, the sales guys Brian is very helpful to help us get a right car, thanks a lot

GREAT SALES PEOPLE MR JEFF DOUCETTE WAS VERY NICE IF YOUR GOING TO PURCHASE A VEHICLE I WOULD CHECK OUT THIS PLACE FIRST GREAT INVENTORY AND GREAT SALESPEOPLE

This is not the first car weve purchased from Mike Foster and Brian Mahan and it wont be the last Im sure. Both of these fine gentlemen have helped us in the past and both helped us once again during our most recent shopping experience. Both Mike and Brian are patient, knowledgeable, friendly and never pushy. They took the time to work with us and answer every question we had as we navigated the buying process and tried to weigh our options. We finally settled on a brand new 2017 GMC Sierra SLT and are so happy that Mike and Brian were there to make sure we got exactly what we wanted! Big shout out to Paul Rowe the GM who has been GREAT to us over the years and to Steve Santosousso in the Service dept. who is top notch as well!! If your looking for a place you can trust that will treat you right and help you find your next vehicle, and every one after this, at a fair price then search no more. Colonial Buick/GMC of Watertown is that place. Just ask for Mike and Brian!

Great people, quick service, would use them again!

Love this place bought 2 cars from here

Another great experience with Colonial GMC ! From start to finish the experience was easy and first rate.... When purchasing any GMC product, why would you buy anywhere else?James L. Eastlack, Rangeley,ME

Love Colonial GMC!!! Brian Mahan, Sam Davis & Richard Stempel are efficient and extremely easy to work with. Ive bought 3 vehicles from them in the last 3 years!!!

Everyone at Colonial Buick/GMC was more than pleasant and professional. My wife and daughter were treated very kindly during our visits and we felt like we were everyones top priority throughout the entire process. We were initially greeted by the General Manager Paul Rowe who set me up right away with Mike Foster. Mike Foster was a very friendly salesperson, and was quite knowledgeable about the GMC brand and in particular, the Terrain model I was interested in. Mike handled the transaction without any high pressure tactics, or redundant sales pitch. Lastly, Richard Stempel handled the final details with finesse and was even able to obtain a better financing package than my credit union had initially offered me. Overall, this was a very good experience for my family and we are extremely happy with the outcome. I have since sent along my co-worker and brother-in-law who have both purchased within a week of my purchase.Jose DiazSatisfied 2015 GMC Terrain OwnerBoston, MA

AVOID AT ALL COSTS.They really only seem to be concerned about their survey and that is it. Check Yelp- Better indication of what you are in for... Slimy and fake people who only care about the survery.

Amazing customer service from experienced, knowledgeable people.

I had a fantastic, personal and very professional plus courteous experience withBrian Mahan at Colonial, GMC in Watertown, Ma.My son had already purchased a vehicle with him and referred me to him..I am so glad he did!!!!

Poor communication and support. Good service regarding the vehicle being fixed.

Mr Brian Mahan made it easy to lease a new truck.He made it easy with no pressure at all.Mr Mahan was very knowledgeable,and explained all the trucks options.If anyone is looking for a Buick or GMCgo to Colonial and see Brian Mahan.

I called and made an appointment for monday, october 13 for a recall on one of my two pontiac vibes. anthony the service manager took me right away. while he was entering my info into the computer, mechanics and other customer service people kept coming in with questions, everything from third party warranty checking to trying to figure out how to get a customers car finished on columbus day, when a large fraction of the staff was on holiday. i was amazed at how complex his job is! anyway, anthony took less than 5 minutes to get the entire order written up, and he checked for other recalls on this car and on my other vibe. he said that the parts were in and i made the appointment for this friday. in and out in about 40 minutes. doesnt get much better than that.

I bought a new gmc truck from colonial gmc in watertown and the sales process was so easy as it always is at any of the colonial dealerships. When Im in the market for a new vehicle I always go to Paul Rowe. I have bought many cars and trucks from him over the years and he has always treated me more than fair. My dad and I went over to colonial gmc back in april 2012 to look at a new gmc 1500 crewcab. They gave me what I wanted for my trade and gave me an incredible price on the new truck. The deal was so good that my dad ended up trading his truck in and bought a new truck also. That day I drove in with my old truck and drove out in my new one. They have great service after the sale. I would recommend everyone to buy from the colonial dealerships. Paul Rowe and Mike Foster make it so easy to buy a new vehicle.

Inexperienced labor. Incorrect diagnoses for $95. Repairs cost 3X what they cost at honest garages.

Great place to relax while waiting for service

Very eager to help people get exactly what need

We agreed on a deal while I was in the office, and agreed on a price to pay with finance and everything else. They said they would fix a couple of issues and complete the deal.After more than a week I just got a call back saying that it would cost an additional $1500 - $2000 if we still wanted to car.Dont do business here!!!

Anthony and Steve all ways take care of me and they work with me as far as time is concernedCopy

Im saddened to hear that Colonial Buick GMC is CLOSING, the people that worked there are loosing their jobs. Thank for your service.
