Walnut Creek Auto Repair

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!

Made appointment to have our Lexus RX inspected before giving it to our son to make sure it was in tip top shape. Did it on line over a weekend and had a confirmation first thing Monday for the next day. On arrival, Tim had read the appointment request and knew why we were there. Very friendly. Very efficient. Called mid day with a report--all looked good, some minor issues that he didn't think needed attention now. When we picked up the car he gave us the mechanic's written report with all the measurements and read outs. Price was quite reasonable. Again had a nice friendly chat. We were extremely satisfied and have a lot of confidence in his knowledge about Japanese cars.
