I could have told you that at least half the cars on "Pimp My Ride" were not legal, just from the few shows that I actually did see. I can't even see how the people doing the work on that show could call themselves professionals; does anybody honestly want to hire somebody whose idea of a custom car is to put a makeup mirror/set/styling salon in the trunk of a car, and have them work on a real car? I wouldn't. "Overhaulin'" is another type of show, with real car guys designing and building the cars. They overplay the taking of the car, the time crunch, and some of the drama, and I don't believe that the work can be done in 7 days (or however many days they are using now), and some of Foose's designs I don't agree with, but at least they aren't putting makeup salons in the trunks of cars.
I don't know if the car is economically rebuildable (by that, I mean that the car can be rebuilt within an affordable range of the son). The damage is pretty bad, but as has oftern been said, with enough money, anything can be done.
