Walnut Creek Auto Repair

Tim has done for me what no one else could do. Roesbery Car Care in Walnut Creek had ruined my electrical system, causing my "check engine" light to be on for a year and leaving me unable to smog my car. After trying three different mechanics with negative results, Tim at Diablo Auto Specialists was the ONLY ONE who was able to fix the problem. He is always courteous and knowledgeable, with A-1 service and reasonable prices. I completely trust him and am grateful for having found him!

It's rare to find an honest mechanic nowadays. Especially as a woman, most mechanics tend to talk down to me and sell me things I don't need. I'm no expert in cars, but I've had to read up on certain things to not get bamboozled! Diablo Auto Specialists are honest and never talked down to me when I took my car in for a suspected leak. Everything they found was what I already suspected, and they made sure to explain exactly what was wrong. I highly recommend them and will use them again.

We have been using Diablo auto for our vehicles for over 6+ years We completely trust Tim’s advice and guidance. Never feel that they advice services to make money. Definitely recommend them!!!

Great service. Seem very honest and dont try to push additional repairs that are not necessary.

Tim squeezed me in when my battery blew. Always thorough, explains all work, and fairly priced.
