When I first got Tillee (2003 Toyota 4Runner) I asked my buddy Jobe where I should take her for service. He was a mechanic but recommended I go to Diablo Automotive and he was correct: they were amazing. But, life can change in an instant and Diablo Automotive is suddenly gone. So, Diablo Auto Specialists have stepped in to pick up where things left off. New location and new owners but the same amazing service.
And in a huge twist of irony, they are located in my buddy's old building. I took our truck there for some potential warranty work last week and although it wasn't clear if the parts were defective, the owner happily made the necessary repairs, which I fully appreciate. I usually do small repairs on my own but for anything that requires talent and experience, this is the new service home for Tillee. Five stars!

I love the honest, helpful and customer service oriented atmosphere. Melissa went above and beyond to try to get my warranty situation sorted out and was extremely communicative every step of the way. The owner made sure the Uber was covered while my car was getting repaired. Service: General repairs & maintenance

This was my first opportunity with Bill. I dropped off my 16' Challenger Hellcat, hoping to diagnose an electrical issue. Bill was great and communicated well. I won't hesitate to bring my vehicle back in the future. Services: Electrical repair, Auto engine diagnostic
