Walnut Creek Auto Repair

Not only is the Specialist’s work at the highest level, and the experience nothing less than exemplary, but you know Tim really cares, and is eager to go the extra mile. Thanks for over 15 years of exceeding my expectations! Craig Beckner Beckner Contracting & Management, Inc. Walnut Creek

Tim & Cathy run a well organized shop with excellent, well-trained technicians. For short appointments, my car is always done by the estimated time Tim gives me. For longer services I can drop it off the night before if I want. They took care of my old Toyota and are my go-to service place for my 2010 RDX. I've never had a problem with it, knock on wood!

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!
