Walnut Creek Auto Repair

Professional, honored my online coupon event after i dropped my truck off. They didn't find the source of my noise, but assured me nothing was wrong. They went above and beyond by lubing my sticky parking brake cable! I had forgot to ask them to look at that, they didn't charge me and I really appreciated it.

Very helpful and efficient during a very upsetting time. Thank you

Diablo Auto did a fantastic job of repairing my car. The person handling my car called me regularly to keep me updated on the progress of the repair. I was given expert knowledge of the repair assessment. I was provided a detailed rundown on how the issue would be addressed. Once the car was repaired (in less time than estimated), the person took extra time to answer my questions on what I can do post-repair.

This is the finest shop in the area; I've lived here for 35 years and have gone to many others - too bad it took me this long to find them. Tim and his crew's work, experience and knowledge are outstanding. They even convinced me to NOT do a brake line upgrade because of complications to the system, saving me money.

Excellent service, as always!

Tim and his team have now rescued three of my vehicles, all of different makes. He was fair and honest on each of my experiences. Thank you DAS!

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.
