Dublin Auto Repair

Don is an excellent mechanic... he recently serviced my 2006 Volvo and did a wonderful job. I am so grateful that I have Don as my mechanic. He always takes the time to explain details to me so I can make an informed decision on what issues need to be addressed and what repairs I can put off.

Great experience, hands down. I am normally very hesitant about taking my car in to get things fixed, because I hate having people overcharge me and fix things that don't need to be fixed. None of this happened here, Don was great and did an excellent job. I am very pleased with the service and I definitely recommend them to anyone looking to get their car fixed!

Don Tupper at Tri Valley Automotive does quality work at a competetive price. My car needed a radiator and an alternator replacement as well as an air conditioning service, Don and his staff had the car done that evening and performing flawlessly, in time for mr to go to work the next morning. I highly recommend them.

Don is Great! I am not terribly auto savy, but Don explains what needs to be done in a way even I can understand. His prices are very competitive, his work is top notch and repairs actually take just as long as he says they will. AMAZING, an auto mechanic that does not lie and your car is ready when promised. You're the best.

FANTASTIC JOB BY Tri-Valley Automotive. First of all, let me mention that I'm an Industrial Maintenance Mechanic with 30 years of experience working on production machinery of all types. I can tell an excellent mechanic because I know what they're doing to my vehicle. I brought my daughter's '95 Volvo in for an AC service. Perfect job, done just right for the right price, quality work, nice people, plus they insist on a free follow-up inspection to make sure the Air Cond. system is continuing it's ice-cold operation. They fit me into their schedule with short notice. My advice is Give Tri-Valley Automotive a call for your next tune-up, oil-change, or any automotive need. You'll be very happy that you found a good reliable honest shop!

I really appreciated that Don not only did a great job on my oil change, but always does a 30 point inspection. When he went over what he found, I appreciated his honesty in advising me about what service needs are coming up, but also for not being pushy. He gave me quotes and left it up to us. He won our business!

I called Don with a transmission problem. I was able to take my truck right over. He told me it would take 2 hours and they were done in 90 minutes so that was awesome also. I highly recommend Tri-Valley Automotive

Tri-Valley Automotive is the best! Don gives fair rates and takes care of you car fast. I trust his judgement. He tells me when I really need things done and what things can wait. He is one of the few trustworthy mechanics. I highly recommend them for all your car needs!

We have used Don for our Volvo with 166,000 miles on it and he keeps it in great condition, as well as for replacing my daughter's entire Honda engine as well as maintaining my Volkswagen. He has worked quickly, efficiently, and inexpensively, always telling us what really needs to be done now, as well as what can wait awhile before being done. I would recommend Don to anyone, he is a great mechanic!
