I was very happy with the service I received at Diablo Auto Specialists. When I called ahead of time to make my appointment, I told Tim that I was concerned about several issues on my car, including my timing belt. He told me that it was important to know what services had already been done to my car in the past (since I'm a fairly new owner), so that his team didn't replace a timing belt that had already been recently replaced. Sure enough, when I dug out the Carmax report, I saw my timing belt had been replaced about 12,000 miles previously, with the previous owner. Tim saved me a pretty significant expense by having me check this. They had my car for a day and did a great job doing the overall maintenance I had asked for. My car is running great, and I didn't pay an arm and a leg to get it all done. I'll definitely be coming back to Tim and his crew in the future.
