Had my car repaired by them yesterday for the first and they were awesome! My car has been giving me trouble lately and now it runs smooth! Thank you!

A very professional, friendly shop with experienced mechanics that doesn’t overcharge (in fact I feel bad paying as little as they charged me, so I’ll be offering more when I pick up my car). Tim is the owner and is extremely helpful, transparent, and knowledgeable. He explains every part of what they’re doing and calls you before changing anything. He doesn’t try to add extra services or rush you to make a decision. I highly recommend this shop for all your regular maintenance and any other servicing.

As usual, it was a pleasure to get my car serviced at Diablo Auto Specialists. Tim and his mechanics keep our three-year-old Subaru and 17-year-old Nissan in top shape, without costing an arm and a leg. I really appreciate the great service!

Tim Stussy and his crew at Diablo Auto Specialists are awesome. We have taken all our cars there for years and have never been disappointed. Tim is an amazing listener and an articulate communicator about the appropriate range of options for needed or recommended repairs. We recommend him and his shop to all our friends!

If you are looking for courteous and honest service for your vehicle this is the place to go. I stopped here from out of town with my check engine light. Tim, the owner, had never met me before and may never see me again but still gave me great service. He was able to diagnose the issue as low on oil, provided me with a quart of oil, cleared the code and sent me on my way. It was easy and relieved me of so much stress for the rest of my drive.

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.
