I've seen that Corvette, too. Not for real, though, just in my Car and Driver calendar. Looks a little odd stretched out so much at the front, but overall, I think it's a great idea.
Oh, and I almost seriously made an offer on a Metropolitan last year. (just like this one) Does your love of Metropolitans have anything to do with being a "Weird Al" fan? That's who I think of whenever I see one!
