Dublin Auto Repair

My experience at Tri-Valley has been like taking my car to a close friend of mine. Don knows the cars really well and gives very honest and reasonable estimates.

Don Tupper takes very good care of not just my car but of my check book too! Personal service performed with integrity and in a timely manner has been my consistant experience with Tri-Valley. It gives me peace of mind to know I can count on Don to take care of my car.

I did a oil change for my mustang and was happy with the service.. The service included the 30-pt check .. Don ( i think the owner) was very informative and frank about the service. He was very prompt on giving feedback after the 30pt check. Thanks a lot and will definitely go to Tri-valley again and will also let my friends about this Auto center.

runs great. Thanks for your help in finding the problem and also with my oil leak. No Leak. I know I don't spend much in the world of car repair but you always make me feel valued and my car runs great. Thanks again..

I've been bringing my cars to Tri-Valley since I moved into the area about 5 years ago. I have found them to be professional, knowledgeable, and reasonably priced. I have no regrets.

Don had my cars clutch done the same day it was scheduled, two hours early. Very happy with the service, at a good price.

Don was very helpful and open about fixing both of our family cars. He was spot on with identifying the necessary maintenance issues. He was great in explaining and helping me filter fact from fiction. He explained all the diagnostics given by "Brand Dealer" and helped me save thousands of dollars avoding unnecessary fixes recommended by the dealership who was trying to sell me a new car. Thanks Don...

Was very happy with the quality of repairs, with the price of the repairs and the timeliness.

Called him Tuesday and had my 4runner towed there for a clutch. Came back Thursday and it was done. Way cheaper than any other closer option, and his service was professional and friendly.

I was in a pinch to get the job done quickly. I called up Don and asked if I could have my vehicle towed there to be fixed. Two days later, I drop by to see how the progress was, and it was finished and working fantastically! I would trust Don with any task he is capable of with any of my vehicles.
