I have found no one in Asheville, though I've gotten to be good friends with Skyland Automotive.
I used High Country 4x4 in Boone to do some stuff on my rig. It was convenient because they came to Asheville, picked up the Jeep via trailer, and returned it a week later. I'm not sure if there's a particular amount you have to spend with them to do that, but it cost me something like $100 round trip.
