I got my car towed to location because of check engine came on. I got my codes read, and emissions came up. I sat hours in the waiting area for them to tell me it was only my spark plugs. The next morning my check engine came back on. I took my car back to the dealership, and they tried to act like the code wasn’t there the day before. They tried to rig my car because my car’s warranty ended Is going to end in Halloween. They didn’t want to do the work because they weren’t getting paid for labor. Honestly, I feel like it was a race thing. I was the only black person, and everyone else was white. They literally treated me horribly. I wouldn’t recommend this location at all.

I found the exact vehicle I was looking for and called to confirm it was at the dealership. I spoke with Ester in sales(Tuesday). After sending over the requested information regarding a potential trade in,I was told I would be contacted. After not receiving a call back I decided to reach back out two days later(Thursday). I was told their system was down. I explained I lived 3.5hrs away and would be in town Friday and needed to get things in order for the potential purchase. Once again I received NO FOLLOW UP.I called again Friday to confirm I was in town and wanted to get the information needed as I was ready to make a purchase. I was then told by Ester that I should have received a call but not the vehicle was sold (Wednesday). A little follow up & communication would have been professional. I could have purchased the vehicle on Wednesday had Ester made a small effort for a Customer. I do not recommend working with this dealership if this is how they train their salespeople to treat customersspending a tremendous amount of money.

I prefer to shop and buy cars online, so I inquired online about a specific vehicle at this dealership. I received MANY sales emails from:Kathryn HarrisInternet Sales SpecialistJohn Thornton Buick GMC1492 N Park StreetCarrollton, GA 30117However, I did not receive an answer to my initial question. I replied immediately to let her know that she did not answer my question. She never responded to my email, but continued to send useless and annoying sales emails. This has become so annoying after 3 months, that I decided to post a review. I feel they have no respect for potential or online customers. I got a great deal on a used Honda from Porsche of Birmingham where I was a valued customer, online and in person.

Isabelle and Joanna were amazing! Staff was very professional and polite. Everyone has been more than helpful!

Was awesome and the staff at Thornton worked hard to complete this sale. I owe the purchase of my Acadia to my local GMC dealership here in Huntsville, AL. As they have none in stock, nor it seems does many, many GMC Dealerships, I called on Bentley GMC Buick here in Huntsville to help me out.And boy, did they ever. I am a long time customer of Bentley so I really appreciated the guidance provided by them in my search to find an Acadia in stock at a Dealership here in the SE USA. I was willing to travel to make a purchase.Thornton did have one in stock that interested me and after numerous, really numerous phone calls with the Salesman, we were able to complete a deal. Imagine then my surprise when he told me they would be delivering my Acadia the following day!Great experience for me, excellent representation of the quality GM standards in the vehicle, and a pleasure to do business with Thornton. Heck, they did all the work, I just had to sign for the car upon delivery. Thanks to all who made this possible.

Stopped in last week to look at a truck I saw on truck trader. Rodney Walker came up and we started conversation about the truck. I have known Rodney for 25 years. He is from a outstanding family. Rodney was professional and assisted beyond and above what was required. Got my money from Navy Federal Credit Union and had a trade in.

What a great car buying experience and a customer experience that went above and beyond. Let me explain. Car dealerships that stand behind their used car when a problem exists and are willing to solve the problem in a short period of time are the ones i want to deal with. Ken in sales and Todd in Service made this experience possible. When the battery went dead at no fault of their own, on the car, they sent a mechanic to my residence (30 miles away) to not only jump it, but also left me a courtesy car when the mechanic took the car back to the shop. Now you tell me, name another dealership that will go above and beyond for a customer and stand behind their product. My car was brought back to my residence by the mechanic and it has run top notch since. I have trained customer service throughout the country and have to let everyone know that this is the epitome of Great Service! The team at John ThorntonBuick GMC should be proud.

If I could give a 1/3rd of a star I wouldn’t do that. The amount of cars on the lot shows enough, so you can imagine the customer service! Especially the unknowledgeable service advisor who said it’s normal for a 2019 vehicle to burn oil. Brought in for several oil consumption tests and have been burning 2qts of oil every 1k miles. Now that they’ve done the oil change and it’s been driven almost 2k miles there’s no oil been burned. Stated I’ve been here numerous times and if there’s no interest then I’ll go somewhere else, his response was “ok do that “ no sir I wanna help you!! So if you want a powerwheel or any other kids toy looked at dealing with ERIC RIVERIA I wouldn’t suggest!!! Hope you see this too sir!! Didn’t buy from Ken rupp, didn’t buy from walkers and dang sure won’t from John Thornton!

I had a great experience. I felt welcomed and very comfortable during my time they. I bought a 2014 Nissan Murano. They had the car ready for me to test drive when I got there. The car was clean inside and out. I would buy from them again.

John Thornton Cadillac, Carrollton, Georgia, is a customer focused business. Each of the customer service representatives, with whom my husband and I interacted, were sincerely courteous, highly professional and gave us a complete description of what our truck’s maintenance costs would entail. Since we purchased the preowned truck a year ago, to haul behind our RV Bus, we have been very satisfied owners.

One of the best home town experiences Ive had in a long time. Some may say women need to take their man with them to purchase a new vehicle but this team blew that thought out of the water. They were very professional but down to earth. I spent half the day with one person who stayed with me through my entire buying experience. I was never pressured into any discussions nor was I redirected from the vehicle I wanted. I was offered lunch, they washed my new truck and filled the fuel tank. Very clean facilities. I am very happy with my truck buying experience and my new truck. Thank you John Thornton team. Yall rock. 😊😉😁

Im 62 years old and have bought a lot of vehicles in my life. This was the best buying experience Ive ever had from start to finish. Thank you!

Great overall dealership. Really easy buying experience. Everyone was great and knowledgeable. AJ my salesman really went over and beyond to answer all my questions.

The best experience ever from the step out of my car all the way to wet ink on the paper. Salesman mr Cooley was extremely knowledgeable about the car. We were extremely comfortable with our experience. I have already recommended two friends to visit the dealership to search out Mr Cooley and the man in the corner office that walks you through all the options with financing. The corner office man was kind and understanding with me. He explained all my options. My experience will lead my family back to these two. Thank you for such a great experience!!

My husband and I had a wonderful experience. Jon and Larry took great care of us. We felt super comfortable and not overwhelmed at all. It was a very relaxed and welcoming environment. No one tried to hassle us or talk us into something we couldn’t afford which was a breath of fresh air. We’ve bought multiple vehicles before from different dealerships and have never been treated so well. They made the process so easy and we absolutely love our car! Highly recommend!!

Absolute worse dealership. Drove an hour and half to buy a Yukon that I made sure they had and haven’t sold it yet. Salesmen was even texting me while I was on the way. I got there and told me “we just sold it”. Also I couldn’t use my credit Union or pay cash. I had to use their financing. Some shady business going on there. Would NOT recommend.

Great stock. Vehicles all kept clean, looking ready to roll off the lot. The sales rep that helped me, Shane, was knowledgable, professional, and just the right amount of wanting to make a deal but also letting me drive the decision. Weve bought from them before.

Great service as always. Technician ready to assist at the scheduled appointment time with no waiting. All employees pleasant and attentive.

Very good service from all the folks who helped me I think I got a fair deal [after some negotiating] I am overall pleased with my experience at this dealer

Mr. Bill Kent was very knowledgeable, kind and patient. Best buying experience ever.

Anthony was great. Everyone we came in contact with was very friendly. We were pleased with the whole experience.

Best car buying experience of my life! AJ was amazing and I will be returning.

AJ was very helpful with vehicle information and showing us options. Shane and Matthew were also great to work with after the sale. Would definitely go there again for a car purchase.

My overall experience was outstanding. Everyone involved were true professionals and made me feel like family. The process was smooth and stress free.

I was in for oil change. The guy at the desk treated me like royalty. He was so kind. A rarity in this day and time. My experience was perfect. Thank you.

Our Salesperson Anthony Gray was great. Between him and the credit manager they made our purchase smooth and uncomplicated. Very Very satisfied with our Experience.

Glenn found the exact vehicle that I had been looking for and made the process very easy.

Made purchasing a truck a breeze. Thank you Rodney Walker and the crew for all your help. He made the process easy and stress free. Gave me a great price on my trade. Went above and beyond to make sure I was happy. Highly recommend thIs dealership for used and new vehicles. Thank you!

Everyone I came in contact with at the John Thornton Cadillac treated me like I was someone special. Ryan wanted to get me exactly what I wanted. Matthew went through the options and ordered me exactly what I requested. Mike took care of my paperwork and Shannon helped me with the financing. They made it a breeze and I have been telling the story to the numerous people who have gone out of there way to complement me on the new truck. The one word that comes to mind about the dealership is Excellence.

John Thorton Gmc made it super easy I was in and out in probably 10 minutes everything was pretty much done over the phone gave me the best price on my 2021 Yukon XL it was definitely worth a travel especially to deal with this dealership they made everything super easy and great prices I will do business with them again

I could not have asked for a better sales guy. AJ Cooley took all the time we needed to decide on which vehicle I wanted to purchase. He opened the cars and left us to look and then drive them. We spent a lot of time there Saturday and ended up with a New 2021 Envision. Thank You again AJ.

I have purchased 6 vehicles from the Thornton family over the last 25 years. It has always been a pleasure and is the reason I have been a repeat customer. I have never left their dealership feeling like a didn’t get a good deal or that I had been taken advantage of. I will always be a Thornton customer. My sales person for this last purchase of a 2021 GMC truck was Joanna Thigpen and she was outstanding! Very courteous, knowledgeable about the product that she was selling and had a great customer service type of work ethic.

Service center was not helpful and will over charge on time it takes to replace parts. Took my vehicle the day after I bought it to the service center due to a noise from the engine. Service center stated there was nothing wrong and it was working properly. Had to take my vehicle back after one month due to the noise becoming worse. Service center wanted to over charge and then stated there was no records of the vehicle being brought in a month prior. Showing us that they either did not even check the vehicle the first time or they do not keep proper records. We will never use the service center again. We will never buy another vehicle from the dealership. We will always tell other people to not buy from the dealership either. My family has bought multiple cars from John Thornton before, we no longer will use them. Worst service ever.

Jon Day was excellent! So accommodating and kind. Great experience start to finish.

My service appointment was amazing. I arrived a little early and my service was completed in a timely manner. Person at service counter was cordial and helpful. He showed me to the waiting room and pointed out location of the bathroom and vending machines.

John Thornton Buick GMC is NOT the place to visit to make a purchase. This dealership is very unethical and chooses who they want to do business with; before I arrived it was all good everything was in place for me to make a purchase. Once they saw me they no longer wanted to do business and this is after I drove 2hrs. Keep in mind I do have over an 800 credit score, there was NO trade-in and pricing wasn’t an issue… Please think before buying here. They don’t answer the phone, won’t call you back and when transferred they don’t pick up. All of these people I will pray for because God heals and he still loves them but I won’t go back. Be Blessed!

When I pulled into the service department my tire was going flat. The young man who helped me was exceptional. So thankful for his quick response. His customer service makes him a “keeper.”

Made the purchase completely online and over the phone. It was a great experience all around! We live 130 miles away in another state, yet they still delivered the vehicle to us at no extra cost! Great all around experience!

Salesman did excellent jobfinance dept was very informativedealership did what they agreed

Anthony and the whole team were great! Everything went smooth and there were no surprises.

It was good. They honored my request on the trade-in value and also worked with me on waiting on checks to clear. Vey nice and cooperative.Now, on the down side. Over 3 and a half hours to complete the sale. Way, way too long. They need to improve the throughput to get people out of the door quickly.

I feel that 2+ hours is way to long for a scheduled oil change

Easiest process I had ever had on purchasing a new vehicle....... Since it had to be ordered, I had to depend on my saleslady that everything that was discussed at the beginning on ordering the added extras and final price was dead on with no hiccups...... Thinking on purchasing another for my son and will definitely be using Isabel again for a no nonsense transaction........B Thames

I shopped prices among at least 7 local dealerships and found John Thorntons pricing to be far better than the competition. Customer service was excellent, answering all of my (many) questions, responding quickly, and going the extra mile to ensure I got exactly what I wanted. Drove well over an hour to purchase from them and would do it again. Ask for Joanna!

Great buying experience. Awesome sales and finance staff. I have already referred someone and they bought a vehicle yesterday!!

Everyone was extremely nice and if after the sale goes as well, we will be back in the future.The thing I liked most was you did not try to oversell the vehicle.

Joanna Thigpen was the sales person and she was an absolute delight to work with on the purchase of the new 2021 GMC Canyon. She knew the auto, did not push, assisted with any information towards the GM rewards and was the type employee I would hire. There were other folks that assisted on the delivery of the auto. Matthew, who was excellent going through the set up of the phone and other information on the auto. The gentleman who went through the finance paperwork explained each sheet, made it easy to follow and was excellent at his job. Again, everyone was extremely easy to work with and no one pushed the sale.Each person that we worked with was excellent at their jobs and your folks made it the BEST auto purchase experience. It was actually a pleasant day!My wife really likes HER truck! Thank You

We had a great experience purchasing our new Buick. The salesperson who handled our purchase was knowledgeable, personable, and effective without applying any pressure. We felt we were treated fairly throughout the process. I would recommend this dealership to anyone looking to get a good price on a Cadillac or Buick while still receiving great service and low-pressure salesmanship.

Just wanted to say what a wonderful experience we had at Thornton Buick GMC. We were looking for a truck for our son who is about to turn 16. Rodney Walker was very professional, knowledgeable and made us feel right at home and comfortable while making our purchase. I would highly recommend asking for Rodney Walker if you are looking for a good used vehicle. We also had a pleasant experience with Shannon Cheatwood in the finance department. Thanks to both gentlemen for making it a pleasant experience.

Zach Robinson, the General Manager has put together a great sales team. Rodney Walker my sales rep did a outstanding job helping with vehicle information, loan process, ordering accessories and deliver of the vehicle. I have bought several vehicles from the dealership and they do a very good job. Thanks.

When I drove up for service I was met promptly by employee who carried my car to service bay. My oil was changed promptly and I was only there about 30 minutes. All personnel were friendly and helpful.

They were able to take me without an appointment. Solved the issue that prompted the service visit.

Every phase was delightful!. Everyone there was very courteous and patient and made my experience easy. I drove several cars before I decided on my Arcadia. Thanks

Spoke with them 4-5 times in order to arrange an appointment to purchase vehicle. They said theyd have it out and cleaned up and ready to go for me. Took off work early and drove an hour and a half to go get the vehicle to be there before they close at 6. Showed up and told me they sold the vehicle a few hours before and didnt hold it for me. They didnt even have the decency to call and tell me. Their response was just oh were sorry about that, well call if we get another one like it on the lot. I told them not to even waste of time, theres no chance Id ever by from them. Wouldnt recommend to anyone.

Everyone there is always willing to help you and is very respectful

Advertised a price and then said it was a price mistake and the internet department couldn’t correct the price. It take over a day to get the price from them. They also said you were required to trade a.car on for some of the discounts. Avoid them at all costs. Shady dealer.

I had a great experience at Thornton with my recent used vehicle purchase. I got a great car at a great price. The sales process was quick and simple—with no pressure. Bill Kent was my salesman and was terrific!

Love these guys I go here for my oil changes and my wife just got a car from them today, all of our vehicles we have gotten here always satisfied greatest service

I bought a 2019 Ford F-150.After the purchase of the truck the dealership took it to be detailed before I drove off. Mind you it was raining pretty heavily. Needless to say it was subpar for a detail. It still had the same dust on the dash as I saw when I bought the truck. Once I got home I found to go lids under the floor mats. Also found fast food condiments under the floor mats in the rear seats. Moral of the story the used car side of this dealership is not top notch for customer service . Look over your used car very thorough before purchase.

Isabelle, Matthew, and Shannon were all amazing. They made the truck buying process seamless. Thank you all so much for an amazing experience. And John Thornton himself of course. Thank you sir.

Isabelle was absolutely stellar!! She took care of everything for me and made the buying process super easy! Fantastic staff!!

Ken was fantastic. It was an easy process and pleasant experience. Fair trade-in value for my old truck, and a great price on my new GMC Canyon. Would highly recommend, and I will in the future.

Made my first purchase from this dealership a couple weeks ago and my sales rep was great. Started with a phone call, car was ready to view and drive upon arrival. Overall a pleasant experience with the exception of closing on the loan which took forever. I am assuming they only have one person to complete the final paperwork which takes at least an hour so we spent 2 hours waiting for our turn to spend an hour signing papers. But the deal on the vehicle and the sales rep made that worth the wait. We would definitely use them again

Worked me into their busy schedule in a timely manner providing a solution to the problem!

Great customer service!! Respectful and caring. Helpful in all aspects of purchase

I drove to this dealership all the way from Alabama specifically for the best price possible & that is exactly what they have. They are quick and answer all the questions that you need to know. Ryan is great, super friendly and kind. I recommend this dealership to everyone! This is the best deal, and BY FAR the best car buying experience.

Seems like every time you carry vehicle in for repairs or service you have to carry it back to have problems fixed after repairing the vehicle. some of the craziest answers I have ever heard about some of the causes of mechanical problems! Not using brakes hard enough, using brakes to hard, using wrong tire shine, on and on with excuses.

The dealership did not pay off my trade in on time and I am making a payment on my trade in that they sold 2.5 weeks ago. They knew this yesterday and didn’t inform me until I found I have a payment due on a car I have not owned in 3 weeks. The sales agent doesn’t return messages and they don’t follow up afterwards with the customer. They strictly care about the sell not the customer. Don’t be fooled!And then they try to tell lies about the customer to cover up their mistakes.Do not do business with liars!! In process of finding out why my trade in was not paid off yet I heard several different lies about the balance and what had happened. The truth was they mailed the payment to the wrong address and didnt bother letting me know. Had they told the truth in the beginning I most likely would not have been this upset but I hate a liar.

Excellent service again. Will continue to use them for all my service needs.

I had a great experience at John Thorton GMC and Jon Day especially!! Helped me get into the truck I wanted even all the way in North Alabama! Highly recommend! I will be back

Everyone at the dealership is professional, has tremendous product knowledge and outstanding customer service.

I was extremely satisfied with the courtesy of everyone I dealt with to complete my purchase. My sales person was very courteous and also knowledgeable. I have purchased several new vehicles from different dealers . This is the first time I was satisfied to leave with a new vehicle the same visit.

We just bought a used buick enclave from them. The trade in and negotiation process was quite simple, but I would be lying if I said the financing piece was a breeze. Its 2021, tax time, and many people just got a stimulus...so it took FOREVER to finalize our deal because of the sheer volume of people waiting to buy a car. With all of that being said, we bought our car and noticed a wabble in the steering wheel while driving home. We called our salesman (huge shout out to Ken) the next day and he arranged for us to bring it back in to get it fixed. They didnt have to do that, but they care about their customers and that should be commended. Go buy a car from them!

Most ausomm place to do business Anthony gray was a great salesman to work with in and out in about 30 minutes and Mathew went over the car with my wife showing her how lt works great job guys

I never imagined a car buying experience as incredible as this one! It was so easy, it almost seemed unreal! The team was absolutely exceptional! Everyone was so kind, and helpful! Ryan Dodson was an absolute pleasure to work with. 5 stars isn’t enough to justify the amazing experience! Well done on gaining a customer for life!

Best price I could find in Ga. Everyone at the dealership was great. Would recommend anyone looking for GMC truck to give them a call.

I called for a service, They got me in at the first available appointment. I bought my truck there and was well please with the job.

Awesome service every time.

Always friendly and professional.

Dawn Jackson was my agent. We had so much fun. She is a gem!! She made my buying experience most enjoyable! She was very knowledgeable of the Acadia Denali that I purchased and went over every detail thoroughly!

The service staff was friendly and efficient and the waiting area is comfortable. I will most likely be using John Thornton GMC for my truck services that I cannot do myself from now on. I highly recommend them if you are in the Carrollton, GA area.

Bill Kent is AWESOME!! He was extremely helpful, and he took great care of us! I love my new truck

Working with Bill is always a pleasure. He makes it convenient for me to do business. The whole staff at John Thornton Buick GMC Cadillac treats me like family. This is my sixth vehicle I have bought from this store and I definitely got what I wanted. A big thank you to Bill for the great experience.

Best experience at a dealership in a long time. Mr. Bill Kent was honest, straightforward and very professional.

I had a very pleasant experience the salesman Anthony Gray was very polite and very knowledgeable and I’m happy with my 2020 Buick Encore GX

Great experience! The sales associate I dealt with was friendly and helpful. Will definitely use again in the future!

Best car buying experience that I’ve had in many years. Issabelle did a fabulous job!!

I looked online at the John thornton GMC website for a truck that I want to buy. I found John Thornton GMC advertising the 1500 AT4 I wanted for $50k. I called and asked is the truck available as the truck was in transit from the manufacturer. I was told yes by the salesman, after which I filled out a credit app. I have over a 750 credit score, I live 70 miles away and did this before over the phone in addition to internet purchasing a car. I never received a phone call back. I had to call them only to be told well call you back. After i get a phone call back 5 hours later, I get an simultaneous email with the truck, $20k added to the price then discounted $10k, and the truck was still $10k over the advertised price. I was asking what is this, the sales manager tells me, oh the truck you wanted is sold so we have this one, and heres the deal. Come to find out the trucks they advertise are false advertisements to get customers and not the actual prices. The trucks they advertised were below the starting price which is false, misleading advertising. Not only that, my credit was ran, then wouldnt even tell me what interest rate I could get because I need to talk to a sales manager first but I was talking to a supposed Sales Manager After talking to a sales “manager” she says, oh I cant tell you that because you need to drive 70 miles, come in and talk to a sales manager. She proceeds to tell me lets get you financed with GM for this truck I didn’t want, $20K over the asking price discounted $10k still 10k over. No, No, No. dont buy from this dealer you will get the run around like I did and pay more. I went to Jim Ellis, the salesman found the truck in transit from the factory made the deal, took my information and called me when it came in. In was in and out in 30 30-45 minutes.

The salesman and finance manager what some of the best guys Ive dealt with in a long time at a dealership they work with you explain everything to me about my deal and bought the truck I was purchasing.

Everything so smooth and everyone friendly and helpful

Nice place seemed like a nice salesperson. Even though I didnt buy from them I would shop with them in the future.

Every person I delt with was very considerate and knowledgable about your vehicles.

Easy to schedule, fast and reliable

STAFF WAS FRIENDLY AND SERVICE WAS PRETTY QUICK. I WAITED THERE WHILE THEY CHANGED OIL, ROTATED TIRES AND REPLEACED WINSHIELD WIPERS ON MY 2019 TRAVERSE, IN AND OUT IN LESS THEN 1 HOUR

Bought my car from south Florida. Anthony was awesome!!! Beyond my expectations. Will definitely purchase more vehicles from him and this dealership.

Great, until we got to financing, I felt there were hidden charges and add ons that i was had to accept which drove my monthly price up, but by then I wanted the car. I really wish I had known about those before going into signing for the car

Eric called me and explained exactly what was wrong and what he was doing. They kept the vehicle for the length of time promised. All was good.

Everyone is always smiling and courteous.

Edit: see below, found out there wasnt an issue with the dealers gas pump but with the filler neck in the car to where itll only take 1/4 gallon of gas at a time then shut off the pump, and even though the sale was already finalized they didnt tell us. The car is mechanically sound but I dont appreciate the lack of communication or even investigation on their part.We came to look at a specific pre-owned car, and were very pleased. Rodney made the process extremely easy for us, and was very friendly and patient while we balanced the purchase process and entertaining our 2 year old. On top of that, they mentioned topping off the tank but later realized their gas pump was broken, so Rodney gave us cash from his own wallet to be sure we were taken care of. We are not the type to demand anything like that and initially refused the money, but Rodney insisted that the dealership always follows through with what they say, and that we take the $5. So overall our general experience was good, Rodney himself was great, and we love the car!

I bought a 2017 GMC Sierra. We test drove it on a day that was very cold. It warmed up over the weekend and the ac did not work. They did not care to make the repair for me. I won’t go back.
