I dont use a "BMW" mechanic per say. The guy I use services anything from garbage trucks to hot rods to Luminas. Davis Auto located in between Mt. Airy and Dobson. He works at his own pace so its not a ill drop it off and pick it up in a day or two but I've never mind cause I have a Mini to revert back to driving. Hes not for the faint of heart type that only wants a BMW branded tech to touch their car, not saying that that's wrong just this guy gets it done and I trust him.
