Walnut Creek Auto Repair

Very professional and friendly

Diablo Auto truly impressed me with their exceptional service on my Mercedes Benz. The mechanics exhibited remarkable efficiency, ensuring a swift turnaround without compromising quality. Not only was their service fast, but also surprisingly affordable, which is a rare find for luxury car maintenance. Trustworthiness is paramount in the automotive industry, and Diablo Auto earns full marks in that regard. Their transparent communication and honest approach instilled confidence. I wholeheartedly recommend Diablo Auto for anyone seeking reliable, cost-effective, and trustworthy mechanics. My experience reflects their commitment to excellence, making them my go-to choice for future auto needs.

This was a 60,000 mile service.

This was my first time using their service and it was fantastic. They diagnosed my Hybrids problem, gave me a quote and their tech Jose fixed it w/in 24hrs (During the Holidays)! Easy online booking process, Jon & Melissa had great communication and I’d definitely recommend this company! #LifeSavers 🙏🏽

I replaced the fender liner on my car. They were friendly and gave me a fair price. As long as they’re around, I don’t think I’ll ever have to go to the car company’s official service center.

I brought my vehicle in for much-needed maintenance and received an incredibly detailed inspection report along with their excellent service! I just picked up my vehicle after a total brake replacement, my second visit here, and I'm so happy with this shop. The estimates and follow-up were so clear and helpful. Thanks so much to the whole team for keeping me advised and on the road! I'll be back!

Bill was great and it was a very easy experience. They are very professional and do excellent work and are fair with their pricing. I will definitely be going back

Unhappy with the Dealership I was going to I decided to find an alternative. I looked up the local repair shops and Diablo Auto had so many good reviews I decided to check it out. I was greeted by Bill Adams and I told him I needed rear brakes. He got my car info and put together an estimate that was substantially better than what l got from the dealership. He said they had a cancellation and could do the job that afternoon. This was a great experience. Everything I read in the reviews was true. Bill is a very friendly and engaging fellow and I knew right away that I was being taken care of by an experienced and knowledgeable person. This will be my go to place from now on.

Quality work at a fair price. Great communication throughout the process. Highly recommend for regular maintenance as well as any size repairs.

Everybody there is friendly and knowledgeable. Explained everything to me and got the work done quickly. Highly recommend!
