Walnut Creek Auto Repair

I have been bringing my Highlander to Tim for service for years for service because he and his team are highly experienced, provide excellent workmanship, and do so at a fair price. When I learned that Tim could also service LEXUS as well, I brought mine in for its minor maintenance, and couldn't be happier for doing so, as it saved me the cost and time of going to the dealership, where I had previously serviced my car. This said, I needed to bring my Highlander to Tim earlier this week because my 5yr old battery had died. As an essential service, Tim's shop was open during the pandemic and he had social distancing measures and other procedures in place to ensure the health and safety of his clients. I am most appreciative of Tim and his team. He is honest, professional, and knowledgeable - and kind. Thanks, Tim!

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 happened to be in Walnut Creek for my son's driving license test earlier this week. At the time of the test, the instructor told him that the left rear light was not working and to go and get it fixed and come back in 20 min. We found Diablo Auto Specialists which is really close to DMV and met Tim Stussi the owner. He immediately called one of his mechanics and got it done for us in under 5 min and at no charge. What a kind and genuine individual he is and we were so lucky to have found him. It was such a positive experience, it totally made my day and my son passed his driver's test as well.

Great service. Done on time. Honest! We love know that we can trust Tim to tell us the truth and give us a fair price.

Very professional. Took great care of my car and explained recommendations thoroughly.

Over more than a decade, Tim has provided consistent, reasonably-priced expert auto care service. I highly recommend Diablo Auto Specialists.

I have complete trust in Tim and his mechanics at Diablo Auto Specialists to take care of my car and the cars of family members. Always great service. I feel lucky!

Not only is the Specialist’s work at the highest level, and the experience nothing less than exemplary, but you know Tim really cares, and is eager to go the extra mile. Thanks for over 15 years of exceeding my expectations! Craig Beckner Beckner Contracting & Management, Inc. Walnut Creek

Tim & Cathy run a well organized shop with excellent, well-trained technicians. For short appointments, my car is always done by the estimated time Tim gives me. For longer services I can drop it off the night before if I want. They took care of my old Toyota and are my go-to service place for my 2010 RDX. I've never had a problem with it, knock on wood!

Tim has consistently provided excellent customer service and very competent work on my Subaru that he kept running in great condition for 18 years. He is honest, trustworthy and so helpful in explaining what’s needed and what isn’t needed to be done. I recommend him and his staff highly.
