It’s pretty much your average auto mechanic. From what I understand there are 3 guys: Bill, Rick, and Rich. Rick helped me. Diagnosis took 2 days. Once he identified the problem he quoted $ 450 for part and labor of replacing my distributor. Instead I bought the part myself(AutoZone $ 130) and paid him $ 165 for labor. I was pleasantly surprised when I showed up at the shop with the part to find he had already bought the part and fixed my car, and I simply handed him the part I just purchased, paid, and drove off. He also fixed a leak in my fuel filter while he was at it.
