This car is one of the most reviled of all time. In addition to being on every automotive hate list, it has the dubious honor of being number one in a book called "Crap Cars." The original Mustang muscle car was unarguably cool, while the Ford Pinto was not. Why not mash 'em up and see what you get? Here's why not: The Mustang II shared the Pinto's notorious gas tank design. You know, the one that blew up like a Michael Bay stunt car when it was rear-ended. And thanks to the oil embargo of the 1970s, the Mustang II got a spindly little engine. The chrome horse on the grille could probably outrun this car -- and it's inanimate.
