Walnut Creek Auto Repair

Tim has consistently provided excellent customer service and very competent work on my Subaru that he kept running in great condition for 18 years. He is honest, trustworthy and so helpful in explaining what’s needed and what isn’t needed to be done. I recommend him and his staff highly.

Tim was nice to work with, clean shop, convenient location, reasonable prices, job completed on time

I brought in my 02 Subaru wrx with road noise that Tim immediately diagnosed as a bad wheel bearing. He gave me an estimate to press in a new one, replace 2 seals, install 2 slotted rotors and new pads (that I supplied) and change my synthetic oil for 1050 total. By the end of the day, the car was ready, riding and braking smoothly. 225K miles and counting.

Great service with a smile. Trustworthy and efficient. I think I just found my new mechanic.

This was my first time here, and the first time at an auto repair shop where I didn't feel ripped off. Tim was amazing! He was very polite, and ensured all of my concerns were answered, and more importantly, only fixed what was needed. Extremely good service, trustworthy, and really listens to the customer.

I visit the shop everyday professionally. Tim is knowledgeable and honest in business dealings.

I am the happiest customer in the whole world! Diablo Auto Specialists took care of all my needs. They were extremely honest and professional! Tim, the manager was absolutely incredible! My Lexus was completely repaired in one day at a very reasonable cost!!!

Excellent service and experience, thank you!

Tim was very accommodating, fair and thorough. Diablo Auto Specialists was recommended to me by a friend who has been a customer for years. It is hard to find a mechanic that you trust.

always reliable!
