Walnut Creek Auto Repair

We are extremely grateful to have reliable, service with incredible integrity.

I was so happy to find a responsive, clean, reputable garage to take care of my Jeep after it went out of service from the Jeep dealership. I was not always happy with the Jeep dealership and their services. I felt very comfortable and excited that Diablo Auto Specialist is close to my home, has good hours and flexibility for dropping off and picking up my jeep, and has a friendly demeanor in the customer service department. I highly recommend this garage if you are looking for an honest evaluation of your vehicle, and worry about being scammed for unnecessary services.

I would refer them to my family! I had an amazing experience. As a woman I tend to be intimidated by mechanics, this group was kind, patient and helpful. My car is running perfectly. I cannot wait to refer to my loved ones.

I always know I am getting honest, quality work with Diablo Auto Specialists. Tim and his team are professional and work is done in a timely manner. As a woman, I know I can trust that I am receiving the best service available and I feel confident that my car (an older one at that) will continue to serve me well based on the assessment Tim gives me. Thanks Tim!

Tim and his team provided a great value to me. Tim is courteous and listens to your concerns. I am very satisfied with the work he and his team did on my vehicle. I think I've found the local mechanic I've been looking for.

Kind, courteous, transparent, timely, competent service. My 15 year old car was inspected and necessary repairs performed, with suggestions regarding lifetime repair scheduling. My list of concerns were addressed clearly without suffering my poor memory to remember to follow-up at pick-up time. I've found a new shop for the household fleet!

Tim at Diablo Auto has been our go to guy for repairs for years, I have some unusual Japanese cars that can be difficult to repair and to source parts for and Tim has always stepped up to the plate. Recently I took my vehicle in for clutch repair, and I was delighted to find out that repairs were not needed, that's a dose of honesty that is rare in the automotive service business.

Thank you Tim (owner) for helping over the phone with my Subaru Forester. I was passing through and called to see if they could help me but it was near the end of the day and they didn’t have time to bring me in. Tim took the time, knowing that I wasn’t going to be able to come into the shop, to help me over the phone diagnosing and offering advice. This speaks to the integrity of this shop. Someone that truly just wants to help people without the need to up sell or make extra cash. Thanks Tim!

Super friendly, honest, and knowledgeable! I trust them. They always give me a complete overview of what was done that was standard, what should be done that isn’t standard, and what can be either put off or left alone because it’s not detrimental to the car.
