My kingdom for a Mustang!
btw, I'm not a fan of rehabilitating Richard. Shakespeare didn't so much exaggerate his misdeeds as change. them. There's a story about him having the intestines slowly removed from a man who had written a pamphlet criticizing him, while the man lived, for instance. After Richard's men stretched out the pamphleteer's intestines, they plucked his still-beating heart out of his chest. The man's last words were, "What? More trouble?"
As to the supposed Tudor revisionism, which Richard's defenders often use to claim that he didn't kill the princes in the tower, the problem with this idea is that the stories circulated while Richard was on the throne, before Henry Tudor ever came to town.
