Called on Thursday, Eric managed to fit me in for an inspection on Friday morning despite the business being packed. Problem diagnosed and engine tested with a proposed solution by Friday afternoon. They even found a potential problem that I wasn't aware of. I authorized the repairs on Friday afternoon right before closing time. Monday morning Isaac calls with an additional recommended repair at a very reasonable price. 1:30 pm on Monday (after they're closed all weekend) they call - car ready to go, test driven, engine completely tested. Intake Manifold, serpentine belt, spark plugs all replaced. Cooling system pressure tested. Unbelievable. Throughout the process they took the time to explain the recommended repairs, parts, etc. Honest, fast, quality repair work done by guys who know their stuff and who'll help you out at a fair price. Just found my go-to mechanics in Paso Robles.
