Well he's pretty much hinting that it could be a Shelby, playing dumb that he has no way to authenticate it...... however in big bold print he spells out if you're stupid enough to bid on it, you bought it. And you can't take legal action for the Shelby implication. Seems pretty sneaky to me. If he was on the up and up he would remove the auction and relist it as a Mustang with a bunch of reproduction parts sold as is with a salvaged title.
