First time customer. Was recommended by business neighbor who knew the owner.Ian is the owner of the shop. When i called the shop for the first time, i spoke to Ian. He was very nice, professional and accommodating. I told him what is the problem with the truck and he immediately point most likely what was the problem. He told me to tow in my truck to his shop and they will do full inspection. After inspection turn out exactly what he was pointed in the Turbo Charger went out. They made estimate and i agreed on repairs. Next think i know he was calling me and telling me that the truck is done, way ahead of the estimated time to be done. I was very happy to hear that. I picked up my truck this morning and it is running great. I wish all the businesses would be like that easy to professional.Thank you Ian. GOB WELL DONE. !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

I am forever grateful for the crew at ETA, we were traveling through town and I blew a coolant line. They were able to get me in and get it fixed at a very reasonable price.Thank You Ian, Josh and MattSincerely,Michael

ETA is by far one of the best shops in Colorado and I highly recommend them. Customer service is outstanding, Ian went above and beyond with our repair and took the time to communicate and address several unrelated issues that were uncovered along the way. We travel over an hour to have Ian and the crew at ETA work on our vehicle and will continue to do so in the future. If youre looking for a top notch shop that stands behind their work, look no further. Keep up the great work guys, thank you for everything!

I was in Parker, Colorado for a horse show and after arriving I noticed my Freightliner Sport Chassis was leaking differential fluid. It was a Friday morning and I was planning to return to my home in Billings, Montana on Sunday morning. It was a holiday weekend and everyone else I called said the soonest they could look at the problem was the following week. Not these guys! They said to bring it in and they would at least look at it. Even though their mother was getting married the next day and they were late to get fitted for their tuxedos they took the time to silicone the leaky axel seal. AND, they waived their one hour service fee! These guys obviously love their business and are dedicated to their customers; even the long distance ones. I highly recommend this shop especially to all the horse people who arrive at the Colorado Horse Park with truck problems!

Best experience! I went in with some vague symptoms, they fixed what was needed, nothing extra. And the technology they use was awesome - a quite on my phone with their findings, and I could choose each item to do or not. Really nice people and a reasonable price! Will definitely bring our other vehicles back too.

These guys are great. I trashed my power stroke on a family trip, they rescued me and got us back on the road fast. Josh and Matt were very knowledgeable and found and fixed the problem that brought me in and found what had caused it saving me from breaking down again.

Great service and price.

Ian is great. Fixed a problem that I didn’t want to deal with and was super helpful. Highly recommended. This will be my go to shop in castle rock!

This shop was highly recommended by a friend who has been using them for years. I took my 1991 Chevy truck there for a bumper to bumper inspection. They told me every that was wrong and what they felt needed to be replaced sooner than later. They also showed me where everything was wrong so I could decide if I wanted to do it myself, which led me to fixing several items myself. They were extremely helpful, professional, and honest. I will have a few items fixed by them that is beyond my ability to do because of tools and skill.I would highly recommended this shop to anybody.

ETA is the only place I will take my diesel. The owners are incredibly knowledgeable, fair, honest and above all timely. I needed my truck in and out and these guys made it happen. If you are looking for a great diesel shop you can stop looking... this is the place to use!!Thx Josh and Matt.

Honest work, reasonable price, quick turn around.

Everyone I interacted with both in-person and over the phone where professional. They took the time to answer all my questions no matter how basic the questions were, since I am new to diesels. I was able to drop my truck off to get the work done and didnt have to wait until the end of the day for a call. They called me as soon as it was done to let me know the truck was ready and even emailed me a copy of the invoice so I could view it before picking up my vehicle.

They were so friendly! They got us in immediately even though we were a drop in. They gave the car a thorough look over and their prices are competitive! They weren’t pushy about repairs, incredibly honest! I willGo to them for any and all automotive needs from here on out!

These guys are great! Very knowledgeable and they tell it like it is. Josh and Ian are great to work with and I feel like I definitely get my moneys worth. Very trust worthy company!! Highly recommend them. I’ve brought two trucks in to them and have another one lined up!!

Took my Dodge Ram Diesel in for repairs and told them I needed it back before Labor Day weekend. Because of Covid the shipping on parts was delayed twice. The parts finally came in at 1:00 Friday on Labor Day weekend. They kept 2 mechanics on duty and stayed late to get them installed. I was able to pick it up at 7:00PM. Because of their commitment to their word our trip was saved and they charged exactly what they quoted me even though there were some unforeseen installation problems. I will definitely use them again.

These guys are the best! Super friendly and very honest. I highly recommend any work you need on any kind of vehicle. Thank you guys for being amazing

I highly recommend ETA. The entire team has the customers needs as the top priority. They are extremely thorough, professional and quality of work is exceptional. The entire experience was top notch, from the inspection to the suggested repairs, reasoning and invoicing and payment. I will use them again! Big thanks to Josh and Ian.

What luck to have found this place. These are the kind of guys I like to say good things about. They showed me a video of every problem my truck had. It was great, thanks guys.

Everyone at ETA was extremely knowledgeable and professional. Even living near the downtown Denver area, I will absolutely go out of my way to work with these guys.

Awesome! The vehicle health check test was very helpful. It showed what was needed now and what I could wait to get fixed. This definitely help me prioritize my repair decisions. Josh and Ian are the best, very personable.

Best diesel guys I have ever used. They Know the 6.0. Went through the do’s and don’ts of the engine and THEY recommended I NOT have them to do what I was thinking has it would be a waste of $ and not accomplish my goals with the truck. Finally found a honest knowledgeable shop.

Our first experience with owners Ian and Josh confirmed they are knowledgeable, fair and professional. They diagnosed our issue as something much more minor than I anticipated and charged a reasonable amount for the repair. I couldnt ask for better service!

Ian and Josh are honest and reliable! They have worked on 3 of my cars and have done a great job with all! I love that they do a full inspection everytime so I know what state my vehicles are in at every visit!

First time using ETA. Just had the oil changed on my F-250 Diesel, they were timely, professional and trustworthy. They will be my “go to” auto mechanics for all vehicles moving forward..

Outstanding service and staff! Done professionally and quick. Would recommend them to anyone and everyone!

An outstanding auto repair shop. These guys really know their stuff, especially when it comes to diesel engines. I highly recommend.

The service received was top notch. They were able to quickly identify a solution to my problem and went the extra mile to make sure it was taken care of quickly.

ETA did some performance upgrades on my Corvette and I was 100% satisfied with all aspects of the work and service.

I went to many places seeking information and got different answers from each shop. Talked with Josh and he took care of everything love the new rims and tires. .

Highly recommend this shop to anyone owning a diesel. Thanks guys!!
