If you want to sell this car to someone who knows the history and is willing to assume the liability. Tell your boss to post it on here for what he paid for it at auction, show the receipt to remove questioning. He's had fun with it for some amount of time, no loss in sell it for cost. You will likely find someone who is willing to turn it into an untitled autocross/drag or track car if the price was right. Too far for me or I may do it my self.
