Walnut Creek Auto Repair

The transmission in my 1998 Honda started to slip so I called Diablo Auto Specialists after reading the great reviews on Yelp to get an appt. I spoke to Tim the owner, he explained what he thought was going on and helped work around my schedule to get me in ASAP. When I went to my appt. Tim knew who I was by my appt. time and remembered everything I'd told him - very personable! I didn't have to wait at all. He took my car into the shop and Mike the mechanic did a test drive, he couldn't duplicate my problem, but agreed to drive with me so I could show him. My transmission didn't slip while driving with Mike, but he gave me his full attention and didn't disregard anything I said. He also gave me advice and said to drop by when my car was acting up. I used to work at a dealer and I can't say we ever gave such great customer service, so I was highly impressed and have already recommended them. Thank you Tim and Mike! :

These guys are awesome. Very clean shop, knowledgable staff. They drop off when they can and there's never any follow-up needed after a service. My last mechanic just couldn't seem to reset the service intervals consistently, requiring an extra trip, this is not an issue with these guys. Highly recommend.

Tim is a really great man that runs his business well. My car broke down last year in WC and called the nearest auto repair shop that towed pretty late. He made some calls and got a tow truck to get my car at a very reasonable price. My cars radiator was busted and had him repair everything and did it very quickly. I knew my way around the hood and what was wrong with the car and yet he still insisted on showing me what exactly happened. Great man! Thanks again for everything.

Tim is now the only person I will trust with my car. He's honest and isn't in business to take advantage of anyone. He's always explained things clearly and never does anything without explaining it first. I am in the process of car shopping and will only get something Tim can work on.

I will only take my truck to Tim. He runs an honest business and always explains things in a language that I understand. I also know that I can call him with minor problems and he'll tell me honestly whether or not I need to bring it in. He won't have me bring it in just so they can charge me to look at it. My roommate had a nightmare experience with another auto shop now closed a few doors down from Diablo Auto Specialists and I suggested she take her car to Tim. They fixed what the nightmare auto shop never seemed able to. They also didn't charge her for the labor fixing what the other auto shop screwed up. When she asked Tim why he would do that when it wasn't his company's fault he just said well, it wasn't your fault either. I don't know many people that would go that far above and beyond what is expected of them. Tim treats his staff and his customers extremely well and I will continue to take my truck to him whenever it needs a tune up.

Owner Tim Stussi provides excellent customer service that is thoughtful, patient and informative. I see no reason to take my family's cars anywhere else, ever.

i brought my car because it was making a strange noise and i had skipped my last major service, so i wanted to get a general tuneup in addition to getting the weird noise checked out. i got the maintenance done first and found out that i needed to replace brake pads and get the rotors machined. i called around a few other places for estimates, including the dealership, and although price-wise diablo auto specialists wasn't the cheapest, i was impressed by the owner tim's willingness to take the time to talk me through my concerns and answer all the questions that i had i had a lot!. also, i like that this shop specializes in hondas and other japanese cars, and is a small mom and pop-type operation so can offer more personalized service. case in point: although they no longer have a shuttle service, they are flexible and willing to work with you if you can't come by to pick your car up before they close. also, they're really close to the WC bart station so you can walk there in a pinch. they actually dropped me off at the bart using my car, but i chose to walk back from the bart to pick up my car in the afternoon. they're very honest too -- a small problem came up while fixing my car, and because it was their fault, they went ahead and took care of it and then notified me, even though i wouldn't have noticed if they hadn't said anything. i definitely would recommend them to anyone looking for a place to get their japanese car serviced.

If you want excellent personalized service for your Acura, Honda, Mazda, Nissan, Toyota, or Subaru, bring your car here. Tim Stussi runs a highly honest operation, and I'll be using him as my mechanic as long as I have a car that he's willing to work on. His shop is spotless and his mechanics are well paid--he even provides health benefits--yet his repair prices are very reasonable. He's always willing to explain the problem in as much detail as I wish, and he never seems to be in a hurry. On one occasion there was still a minor problem after a repair, but he performed the additional work without complaint and without any charge. Thanks Tim!

I brought my honda in here for a timing belt and they had fair prices and very professional. I would go back.
