Walnut Creek Auto Repair

Friendly, personable and best of all quick service! Hats off to Tim & his service team for squeezing me in to get a headlight bulb fixed. Next time I need a vehicle serviced - I'll be calling Diablo Auto Specialist.

always friendly and top notch service

Incredibly honest and straightforward. Tim was very helpful in answering all of my questions. I would highly recommend this shop if you're looking for a trustworthy mechanic.

Totally great experience. Everything was as explained and promised.

I went here a few weeks ago thinking that there was something wrong with my brakes. They checked it out for free, said there was nothing wrong, then refused to let me pay them for their time. SO awesome! I then went there for routine maintenance and it was so easy. Well done, no delays, exactly what I was told the price would be. I am so glad to have found a new mechanic!

I appreciate the honesty that Tim gave towards me about the needs of my car and saved me hundreds on unnecessary repairs! I'll be back for my 90K factory recommend.

Outstanding service and diagnosis by Tim and his crew on a very difficult problem. Tim was very diligent in searching for the causes and solutions. He carefully and thoroughly explained potential causes and the work that was done. This was my first time at Diablo Auto Specialists. Their work exceeded my expectations.

Tim always takes great care of our three Toyotas. He does so with both a professional and a personal touch. Many thanks.

Good, reliable service.
