Walnut Creek Auto Repair

Recently had two vehicles repaired at Diablo Auto Specialists - great service on both. Recently bought a used salvage car (2014 Toyota Camry) and brought in for a service plus thorough check the car. They performed a brake job and resolved some other maintenance issues - runs great and should be reliable for a while. Also brought in our 1998 Ford Expedition - have been taking it here for 10 years and now has almost 260,000 miles. This vehicle also received a brake job, power steering adjustment and other service. Tim and his team do a great job letting you know what you can hold-off on and also what you can let go without sacrificing safety. As this is an old vehicle almost at end of life Tim is reluctant to perform expensive repairs that do not extend the overall life of the vehicle. This demonstrates honesty and integrity.

Diablo Auto Specialists is the only place we will take our vehicles now. Tim is a pleasure to work with, is very fair with his prices, and runs his business very professionally.

A very professional, friendly shop with experienced mechanics that doesn’t overcharge (in fact I feel bad paying as little as they charged me, so I’ll be offering more when I pick up my car). Tim is the owner and is extremely helpful, transparent, and knowledgeable. He explains every part of what they’re doing and calls you before changing anything. He doesn’t try to add extra services or rush you to make a decision. I highly recommend this shop for all your regular maintenance and any other servicing.

Tim is incredible and super customer-focused. I scheduled an appointment and Tim offered the flexibility to adjust my time of arrival, and even taught me a few things about my car that I had yet to learn. Tim is beyond honest, knowledgeable, and has me ready to return for my next scheduled maintenance. I really landed on a gem here, and recommend Diablo Auto Specialists.

We wanted to check out the condition of a used car at a nearby dealer and used Diablo to do the review of its condition. Tim was very thorough in replying to my calls and questions about the car and the findings. He went the extra mile to make recommendations for us as future Subaru owners of what kinds of things to be aware of and he was very positive about the car and the work he does. I would definitely recommend this shop for anything you may need with your cars.

As usual, it was a pleasure to get my car serviced at Diablo Auto Specialists. Tim and his mechanics keep our three-year-old Subaru and 17-year-old Nissan in top shape, without costing an arm and a leg. I really appreciate the great service!

Service is great cost is reasonable

Diablo Auto conducted a used car inspection. I've used this shop for decades and always found them knowledgeable and friendly. On more than one situation they saved me money as well. If you need good professional mechanic who is HONEST, this is your place.

First time at Diablo, Tim was excellent keeping me informed and price was as quoted. Quality repair shop and will return for future repair work.

We had been going to the dealership in Oakland for almost 5 years for our car’s regular maintenance. After moving farther from the city, we decided to try a family-owned auto shop to take care of our car. And so we found Diablo Auto as it has really good reviews and high rating. Making an online appointment was very easy. They send reminders. Check-in and out was smooth. Special instructions (no tire rotation as we do it separately) were followed and the tasks performed on the car were meticulously explained before we leave. We can tell right away that our Subie had the proper maintenance as its engine seems to run more smoothly after. A more personalized customer service is a nice touch as you talk directly with the owner, Tim. My husband will be bringing his Crown Vic next time. We are hoping this is a start of a lasting partnership with Diablo Auto.
