Absolutely, people can ask anything they want for a car, but I'll be a nickel somebody ends up buying the explode-o-mobile for close to the asking price - nostalgia, and all that.
The Pinto is not just an outlier, though - a VW bug from the same era, if in any kind of shape at all, regularly out prices a spider even though they were sadly outdated by then. Heck, one of my favorite cars is the Datsun 1200, the ancestor of (and better looking than) the B210. they made 10X more of those than Alfa's (over a million, in fact), it wasn't a sports car like the Alfa or iconic like the VW, and you can't get one of those for what I paid for my runner '76. They are not much in the market and people who know them love them enough to pay up.
Well, I'm just whining anyway. I like my spider, and wouldn't buy a Pinto if I could get two for a quarter, so it's academic.
