Walnut Creek Auto Repair

I always know I am getting honest, quality work with Diablo Auto Specialists. Tim and his team are professional and work is done in a timely manner. As a woman, I know I can trust that I am receiving the best service available and I feel confident that my car (an older one at that) will continue to serve me well based on the assessment Tim gives me. Thanks Tim!

Tim and his team provided a great value to me. Tim is courteous and listens to your concerns. I am very satisfied with the work he and his team did on my vehicle. I think I've found the local mechanic I've been looking for.

Kind, courteous, transparent, timely, competent service. My 15 year old car was inspected and necessary repairs performed, with suggestions regarding lifetime repair scheduling. My list of concerns were addressed clearly without suffering my poor memory to remember to follow-up at pick-up time. I've found a new shop for the household fleet!

Tim at Diablo Auto has been our go to guy for repairs for years, I have some unusual Japanese cars that can be difficult to repair and to source parts for and Tim has always stepped up to the plate. Recently I took my vehicle in for clutch repair, and I was delighted to find out that repairs were not needed, that's a dose of honesty that is rare in the automotive service business.

Thank you Tim (owner) for helping over the phone with my Subaru Forester. I was passing through and called to see if they could help me but it was near the end of the day and they didn’t have time to bring me in. Tim took the time, knowing that I wasn’t going to be able to come into the shop, to help me over the phone diagnosing and offering advice. This speaks to the integrity of this shop. Someone that truly just wants to help people without the need to up sell or make extra cash. Thanks Tim!

Super friendly, honest, and knowledgeable! I trust them. They always give me a complete overview of what was done that was standard, what should be done that isn’t standard, and what can be either put off or left alone because it’s not detrimental to the car.

After a terrible experience with a honda dealer. I brought my car to Tim, he did the necessary repairs (left out the unnecessary ones recommended by the dealer) quickly and for half the price the dealer quoted. I am thrilled to have found a new car specialist that is honest and does quality work. Thank you again, Tim you saved me over $1000.00.

I’m so glad I found Diablo Auto Specialists. I know I can trust them to use the highest quality products and skilled mechanics to work on my Subaru. Tim, the owner, is always friendly and helpful. And, since it’s only about a 15-minute walk to the Walnut Creek BART station, it’s very convenient to drop off my car before work and pick up after.

Loved the great communication... articulate, personable, and gave me ongoing progress reports (my project was a little more in-depth). This was also the first time I took my car to Diablo Auto Specialist (and Tim). I will 100% be back... but hopefully not too soon😜🤣.
