Walnut Creek Auto Repair

My daughter's car died. Tim got us in right away, diagnosed the problem and we were on our way.

fair prices, clean shop, work performed on time...the reason we've been bringing our cars here for years.

Diablo Auto services all three of our cars. They've always taken great care of us and they are the nicest people in the world.

At the recommendation of a friend, I decided to bring my aging Honda Civic to Diablo Auto Specialists when my transmission was acting up. They were great from start to finish - kind & informative on the phone & in person, I was able to drop off/pick up my car after hours, at my convinience. Tim kept me informed to their progress over the week that it was in their hands, parts were ordered quickly (overnight). Since then, I have brought my car back to fix a chronic AC problem. Come to find out a few weeks later that the problem reoccured so they revisited this situation and found that there was an ajacent problem and fixed it for good - they didn't charge me for this work/parts as they felt they should have found it earlier. These guys work with integrity which is hard to find these days! They have a customer for life - thank you Diablo Auto Specialists!

Tim always makes me feel comfortable about the work being done on my car, and explains it clearly so I know what to expect. The work is always done on time, honestly and professionally!

I was impressed with the quality of service. I particularly liked having everything explained in terms I could understand. I thought I had an oil leak. Tim and Treavor showed me that drainage from the oil filter change was likely the problem. Why didn't the people at the dealer tell me that. I have been complaining for 13 years.

I like supporting small businesses. This place is superb. Great mechanics and lots of helpful advice.

After scaring me to death with a comment about my car possibly experiencing a problem with the head gasket, they continued looking at the car and discovered two bad caps. Those caps were replaced and the car driven several times to verify that it did not overheat. Yea! I have my car back with a minor charge instead of the huge bill I was waiting for. Thanks for the diligence!

Good mechanics are hard to come by.....Diablo Auto Specialists goes above and beyond with their customer service and efficiency.I called in the morning to explain that my AC went out and they said if I bring it in within the hour, they could diagnose the problem. By mid-day, I received a phone call from the owner Tim, who explained thoroughly my AC had a broken hose. They already contacted Subaru to see if they had the replacement hose (specific to my vehicle). Tim said they could have it fixed and back up and running before the day was out! In this East Bay heat wave, that's efficient work, especially when I drive my vehicle for work.

Even though I don't know the first thing about cars, I never feel like I'm being taken advantage of. Tim is always helpful and flexible, and does his best to save you money where he can!
