    You can't go wrong at ADS. Greg, John and the guys treat you like family. The service is always the utmost professional and their expertise takes the guessing out of auto diagnosis and repair; which has saved me thousands over the years and on several cars. They are my sole shop for daily drivers and classic cars.


  • 10/9/15

    I wanted to take a moment to say "thank you" to ADS and Sean. We have always been treated with the utmost respect and received excellent customer service on our visits. Yesterday, we panicked when our engine light came on in our truck--especially since we are going on a short…

    I have been going to ADS for over a decade. These folks are very customer service oriented and thorough in their work. They always let me know ahead of time any additional work that may need to be done and the cost before doing anything. We have always been satisfied with the work done at ADS.


  • 7/12/15

    Sean took great care of me. Had a large job to do, needed motor mounts, AC a timing belt and more. ADS even did some extras; straightened out a bent hub cap, washed the car and cleaned the windows inside and out! Plus, the car runs great now. Highly recommendation ADS! You can trust them!

    Brought my vehicle in for an oil change. They found a couple of minor issues, took the time to fully explain them to me, and then advised on what needed to be done now versus what I could wait on. There was no pressure to make any additional repairs. Really nice and patient guys, and they even let me use an expired coupon. Would definitely recommend them.

    We take our fleet vehicles to ADS. It is critical that trucks/vans are back on the road asap. ADS provides us with a quick turn around for repairs, regular maintenance, tires, etc. The bonus is that the price is competitive, the shop is always clean and the advisors/techs are always the same faces. Highly recommend - always delivers.

    ADS has serviced my truck since 2001. The service guys at the counter get me in and out without the up sell. The shop is always clean and top industry certifications are standard. Don't wast your time looking for a mechanic - these guys are at Chandler Blvd/I10.

We will use ADS for future automotive needs.

    I have been a customer of ADS for over 15 years and have always found them to be professional, honest and hard working. They offewr a very high level of customer service and workmanship. They also stand behind their work 100% I would reccomend ADS 100% regardless of the type of vehicle. The best shop in the state by far.


  • 1/27/14

    I have known the owner of ADS, Greg since 1987. Greg and his staff have always been professional, thorough, competent, and honest. Even after 26 years, the staff continues to amaze me with going above and beyond for customer service. Mason, Greg H, Dale, and the rest of the staff are simply the best. My recent experience with their services is another example of my highest recommendation.


  • 1/24/14

    This vehicle hasn't been started in years. Dropped it off on Monday, picked it up Friday. Runs better than I was expecting. Still needs some minor work which I will contact Mark about soon. Thanks ADS.


  • 1/23/14

    I dropped my car off in the morning with engine trouble and it looked like they had a full lot of cars to work on but they called me by 11 with the diagnosis. Dale was very honest about what was needed and let me know the cost exceeded the value of the car.


  • 1/20/14

    I've been taking my cars to ADS for nearly 20 years now, and that in itself says a lot. These guys have always provided the most professional and friendly service I could possibly imagine; in fact, I can't imagine taking my cars anywhere else. I cannot overstate how highly I regard ADS and its employees, and I'll be taking my cars to them for years to come!

    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.…

    This is my 2nd time using this shop and won't take my car anywhere else. They did some custom work for me and fixed a lot of issues as well as worked pretty hard to find me a new battery at a cheap price. Definitely plan on using them again soon.


  • 3/4/09

    ADS has been servicing my vehicles since 2001. The staff is friendly and very knowledgeable. They stand behind their work and provide excellent service. I would recommend without reservation.


  • 2/27/09

    We have been taking both our Crown Victoria's to ADS for over 7 years. They are very professional and do an excellent job at a very fair price. What more can I say.


  • 2/19/09

    I have been taking my personal auto's and for the last two years running a small fleet of commercial vehicles through ADS for maintenance. The workmanship is the best I have experienced and my CSR, Bob, always calls explaining the problem, the cost and when completed he calls again explaining the outcome. If a mistake is made they stand 100% behind their service offering.


  • 2/19/09

    The staff is friendly, very knowledgable and quick to process the request. Workmanship is excellent. Never had a complaint about the skill of the technicians.


  • 2/17/09

    Excellent shop!! These guys have done many service related repairs/upgrades for me over the last 4 years and I have been totally satisfied everytime! I highly recommend them for any automotive need. Thanks guys!!!

  • 2/5/09

    A great blend of customer service and automotive knowledge. I had the oil changed and asked them to inspect the vehicle for additional preventative maintenance. ADS' prices are not the cheapest in town, but their work is outstanding and they don't rip you off with unnecessary work. Ask for Bob.


  • 1/23/09

    I have had my car repaired and maintained by ADS with the highest qualiity of parts and skill form their mechanics many times since I purchased my car.


  • 1/21/09

    Once again we have used ADS to do the repairs needed to our car. As we have experinced in the past they do a great job on the repair. I would highly recomend them to anyone in need of car or truck repairs.


  • 1/12/09

    I stopped by this shop for propane and ask the saleman if they had wipers for my vehicle. He said yes and that he would be glad to remove mine and then put the new ones on! In this day and age customer service is a thing of the past and I greatl appreciated the extra effort. I plan to return for an oil change soon. Thanks again

    This would be my second time using ADS and both times I have been pleased. I was referred to them by a friend and haven't had any problems. They called me with updates multiple times and kept me informed on what the problem was the cost to fix.


  • 1/9/09

    Service was very thorough. These people are always friendly, and seem very knowledgeable. We never have a problem getting an appointment and the work is done in a timely manner. Our vehicles always come back cleaner then when we drop them off. Have recommended ADS to several friends and relatives.


  • 1/9/09

    My first visit to ADS was due to good reviews when I searched on the internet for a reputable repair shop in my area. I have to say that they are very good. When I want them to take me home, they will and will pick me up when my car is done. They fix what needs to be fixed. I would highly recommend this repair shop!
