I've been there. An old heavy-set lady runs it. She can hardly make it around the house without her oxygen. Lots of stuff pretty interesting stuff. I was warned AFTER i went that they over charge you when you aren't paying attention so be cautious. They are mostly late models although he had an old split camper that I remember being way too expensive for me. The basement is full of new parts and the lot on 411 is most of their project vehicles. All the parts cars are at:
5072 Millsaps Dr, Greenback, TN 37742
The one on 411 is:
6342 Greenback Rd, Greenback, TN
Good luck. Hope someone can revive something from there.
