They tried selling it on ebay several times.
Rock Hill isn't very far from Gastonia, so I doubt it's changed hands.
Looks amazing, but there's no way I'd want to keep it polished. Now brushed with a clear laquer to seal it would be the ticket...
$125K for the only one in the world? Well, there's something to that as well.
