Walnut Creek Auto Repair

Tim and all his guys do a great job. They are professional and care about their customers.

Tim is great to work with, explains everything clearly and they did a great job diagnosing and fixing the Check Engine light on my '97 Expedition which has 311,000 miles. Highly recommended!

Tim is thorough and very fair. He explained everything up-front and stuck with his plan. No added costs for extra work. Tim found several issues, reported them and made recommendations for future work. Everything Tim did was very transparent and above board. We'll be back.

This is an auto shop you can trust. I began going to Diablo Auto Specialists 16 years ago. I had a less than ideal experience at a neighboring auto maintenance and repair business. For my next service I decided to give Diablo Auto Specialists a try. I have never been anywhere else since. Total satisfied with Tim, the owner, and his crew. I am happy to give Diablo Auto Specialists my highest recommendation.

great service, super nice and did the work super fast!

If you are looking for an honest, reliable auto repair and maintenance shop, Diablo Auto is the place to go. We've been bringing our cars to Tim(owner) and his skilled team of mechanics for 15+ years.

Very quick and effective service! They didn't overcharge me or make the problem into something more expensive than it was. Straightforward, good people. I'll definitely be coming back whenever my car needs maintenance or repairs!

Job well done and very friendly and easy to deal with.

As usual, Tim and crew at Diablo Auto did a great job. I've been coming to Diablo Auto for years now. He kept my older car going (a 2001 Honda CRV) for a very long time (200+ miles), so when I recently purchased a newer car I of course wanted to have it checked out with someone I trust. Diablo Auto is always professional. When I have questions I can count on complete answers. I highly recommend the team at Diablo Auto. (It's also a convenient location, near Target in W.C., so I can do some shopping while I wait.)

I have used Diablo Auto Specialist's for over 30 years now. They are always honest and reliable and keep my cars running great! Thank you Tim
