So I figured I would put one of the two Jaguar Sport XJR-15’s I have, on the auction house. Never tried using it before.
Weird thing is, although the cars show up in my garage, they do not show up as available to auction. My other Jaguars showed, but not those two.
Can we not sell legendary vehicles?
The problem, I think, is that it’s a Barn Find. I think there’s a whole thread about it showing up as a reward in Super 7 or something and causing this issue of a duplicate that can’t be removed.
So can these cars be gifted? Can they be deleted?
Darn it!
Thankx Ti 
It doesn’t look like it. This may or may not be the thread I had originally read about it:

Luckily I haven’t done Super 7!
