Not as visually iconic or well known as Janis' Porsche but one of my very favorite muscle cars in the best color combination owned new by one of my favorite rock stars? I'd pay way too much for that. So would a number of other people.

Its more desirable to ME, just because it dovetails my car and music geek tendencies in one vehicle. I love the Bullitt Mustang and chase, and I like Steve McQueen, but I find the rest of the Bullitt movie tedious. I've never been able to sit through the whole thing.
