Walnut Creek Auto Repair

After a terrible experience with a honda dealer. I brought my car to Tim, he did the necessary repairs (left out the unnecessary ones recommended by the dealer) quickly and for half the price the dealer quoted. I am thrilled to have found a new car specialist that is honest and does quality work. Thank you again, Tim you saved me over $1000.00.

I’m so glad I found Diablo Auto Specialists. I know I can trust them to use the highest quality products and skilled mechanics to work on my Subaru. Tim, the owner, is always friendly and helpful. And, since it’s only about a 15-minute walk to the Walnut Creek BART station, it’s very convenient to drop off my car before work and pick up after.

Loved the great communication... articulate, personable, and gave me ongoing progress reports (my project was a little more in-depth). This was also the first time I took my car to Diablo Auto Specialist (and Tim). I will 100% be back... but hopefully not too soon😜🤣.

Excellent customer service! Diablo Auto Specialists always does a great job performing necessary maintenance on my SUV, and fits me into the schedule easily. Thank you Tim and team!

been taking our cars here for years now...wouldn't trust our cars to anyone else. highly recommended.

My experience with Diablo Automotive Specialists was great. I was able to request an appointment online, it was quickly confirmed, and they were ready and waiting for my car on the day of service. Part of my service was for a check engine light for which I was originally quoted a diagnostic fee. After reading the codes, Tim called me to explain the necessary repairs and that they were waiving the diagnostic fee because my particular issue did not require significant effort on their part to diagnose and confirm. They obviously could have charged me since they performed the service requested. I have not had other shop’s waive fees regardless of situation and was impressed by this honest, straightforward, and open approach.

This was just a regular 5,000 mile service.

I happened to be in Walnut Creek for my son's driving license test earlier this week. At the time of the test, the instructor told him that the left rear light was not working and to go and get it fixed and come back in 20 min. We found Diablo Auto Specialists which is really close to DMV and met Tim Stussi the owner. He immediately called one of his mechanics and got it done for us in under 5 min and at no charge. What a kind and genuine individual he is and we were so lucky to have found him. It was such a positive experience, it totally made my day and my son passed his driver's test as well.

Tim and company were able to repair my vehicle quickly and at a great rate. We've been looking for a new mechanic and it looks like we've found a good one!
