Walnut Creek Auto Repair

Wonderful and professional service. We take all of our cars to Diablo Auto Specialists. The work is top-notch at very reasonable prices.

Tim and his mechanics did an excellent and thorough job repairing my transmission. The car was ready earlier than promised and the communications along the way were frequent and detailed. Having worked on many cars myself, I believe Tim's shop and the services he provides is first rate!

Tim has such a personal touch and takes the time to explain the repairs in simple to understand language.

Excellent service, as always! Thanks Tim! Lisa

Tim Stussi is awesome! As a woman and not very knowledgeable about automobiles, it is great to have someone you trust to work on your car. At other places, I have been told something was wrong with my car and got stuck with a high bill and never really knew if they were telling the truth or not. I totally trust Tim and he has done a great job on my car!

I have been a customer of Diablo Auto for several years. I had to have our truck towed to Diablo Auto over the weekend. Tim called us that he received the vehicle on Monday morning, he had to order a special electronic part and the vehicle would have to spend the night in his shop. He kept to his word and called us the next morning that the repair was complete. The price was extremely reasonable and customer service is excellent . I would not hesitate to refer Tim and Diablo Auto to family and friends.

You were very thorough in your evaluation of the car we were considering buying, and you saved us from making a big mistake. Well worth the money spent.

When we needed a good, honest mechanic shop to assess our 2003 Toyota 4Runner, our neighbor (a mechanic who specializes in Saab and Volvo) recommend Diablo Auto Specialist. We have been a Honda family for over 16 years and have a great shop we serviced our cars with, but they specialize in Honda and Acura. As most know, it's difficult and stressful going through the vetting of a new mechanic. First off, Tim was clear and friendly on the phone going over the earliest time slot to fit us in for an appointment, and when we called back to adjust he asked what we needed in order to see what worked. Very efficient. Tim was very good explaining the small details and answering our questions, and friendly with me and my husband. The report included any recommended repairs. I would prefer an itemized estimate on the repair but that was not the main purpose of the visit and perhaps why, and therefor listed as a side note. Thanks for inspection and a great first visit experience! Doris and Chris

Great service. They took the time to explain my car's condition and not pressure me into unneeded extra services and products. I highly recommend these guys!

Always a pleasure letting Tim and crew take care of my car.
