Outstanding experience with the team at ADS!! John Thompson took great care of me and explained in detail the results of my four wheel alignment. Greg (the owner) was kind enough to check on me several times while I was waiting and you can tell that he is passionate about running a top notch business. I would HIGHLY recommend ADS for any automotive repair and will continue to send my business their way. Thanks for a great job ADS!!!

These guys are pros. They are honest, professional, positive, friendly, and they know what they are doing. They are a bit pricer than a few other options in the area, but you get what you pay for. I have learned over the years that if you want to keep your car in good shape, you need to give it the best quality service. These guys are the best.

The mechanics at ADS were professional, honest and extremely helpful. They finished the repair as promised and I have a 2 year warranty on the repair that gives peace of mind!

Took my 2010 Dodge Challenger SRT8 in for a custom tune and dyno. I did enough research on my own before taking the car in to a shop. I could tell from my conversation with them that they really know what they are talking about. Mike was my technician and he did a super job. Now I get the HP out of my Challenger that one would expect from a 6.1 Hemi! I will definately go back for any future mods!

I am a long-time customer of ADS (since 1998) and have had lots of work done there over the years, regular maintenance and various repairs on 7 different vehicles of all types and ages. ADS has nearly always done the job right and on time . . when they don't, they still make sure that I'm satisfied. The owner (Greg) and his entire staff are very knowledgeable and professional. Most recently, John Thompson (Service Manager) personally checked the vital fluids in a truck that I seldom drive and was having a heater core replace in. John found my oil level to be dangerously low, added the necessary oil to fill it and then let me know about it. I could have very easily blown up the engine if it had not been for his caring and effective customer service. Of course, I will continue to highly recommend ADS to anyone needing auto service from a trustworthy, capable organization.

When my automobile developed an oil leak that others said would be expensive to repair, I was refered to ADS. Having just moved here from Hawaii, I needed to find someone I could trust.

I have other automotive repair and maintenance work for them to do. Thank you ADS for having great service.

Dave was very professional and helpful with what I needed to get fixed. He didn't push anything on me that didn't need to be done, but was informative on what maintenance options I might need. I would say that the initial price $96 just to find out what the problem was is a little steep and almost turned me towards finding other alternatives. Other than that, the service was great.

A friend recommended ADS to me due to not knowing any repair shops in area. I live in Tucson but this vehicle was up here at the time. My friend had a good experience with them with his Tahoe so I dropped off my Jimmy. Friendly and professional. I needed to leave my vehicle there all week due to not being in town and they were very accommodating as well.

After submitting my first review stating I was disappointed ADS did not clean the area where the radiator fluid spilled out, the actual owner of the company called me first thing Monday morning saying he will personally pick up my car from my place of work and clean the engine area and return my car to me. I was completely impressed with this and happy to accept his offer. I will be bringing my car back to ADS for future service! Thanks guys!

Brought vehicle in for routine oil/filter/lube change. I was on tight time schedule and they did their best to accommodate. I previously brought the vehicle in for a battery problem that should have been fixed by the Honda dealership. Dave and Bob are tremendously helpful. In this case, Bob not only had the battery replaced quickly, but also went the extra mile to contact Honda to reset the codes for the radio, etc. I originally came to ADS based on a friend's recommendation and would do the same for another friend.

I was referred to ADS by a friend who had previous work done. Me not knowing anything about exhaust systems and needing Exhaust Class 101 met with John. John spent a lot of time educating me on what I was getting and what was available for my Mustang. I learned of other options that were available to me for improving the HP and overall performance of my mustang. The shop is outstandingly clean. My exhaust system was ordered on a Wednesday. I was told the system would be in on Friday and he would call. On Friday, I received a call "as promised" and work was complete within 3 hours of that call to me. When dropping & picking up my car I was given a courtesy ride to and from work. I had the opportunity to speak to other staff members at ADS and all were professional & outstanding. Definitely will have them do further work to my Mustang. ADS is one I can Trust !! Thank you !

The people were courteous, knowledgeable and friendly and the total out the door was exactly what they quoted me. My car needed a new radiator, it had cracked on the top and was leaking fluid which gives off a burning maple syrup smell. When I got the car home Friday night and pulled in the garage, there it was again, that powerful burning smell, I thought for sure a hose disconnected or something went wrong, turns out they never cleaned off the area when they were done with the job, all the old burnt residue was still under the hood. I now need to take my car to get the engine cleaned.

I received great service from the Manager of the shop John. My car broke down at the Circle K down the street from the shop. John just happened to be going into Circle k and offered to help fix my car. He was not able to fix my car in the parking lot because he did not have the right tools. John did tow my car back to the shop and saved me $ by not having to pay for towing. John had the problem fixed and me on my way in an hour. John help me out by getting me in and out and I was able to finish my work for the day. I would recamend ADS to anyone who ever needs work done on their cars.

My family has been using the services of ADS for many years now. They are a terrific group of automotive experts. They are very concerned about doing an excellent job on every vehicle that the work on. Today, I went in for a simple oil change type of maintenence. They also noticed that the transmission fluid was looking brown and needed to be flushed and refilled. Now, when they tell me at ADS that some work needs to be done, I trust what they say. I know it is something that is required, not just a way for them to charge extra for more stuff. I do know that they are honest and always do a good job. I am very pleased with the many years of service that ADS has provided. I would always support this company, and would suggest ADS to anyone who needs a good mechanic. Jim

In a world of shady car repair shops I had a great experience with ADS. It's hard to find someone you can trust so I typically go to a car repair shop and play "dumb" when I need a repair to see if they will try to take advantage of me. I had none of that at ADS. They were professional, courteous, and more importantly, honest about their assessment of my vehicle and the prices were more than reasonable. I would definitely recommend this shop.
