An interesting aside is that there was apparently another alloy bodied car, it lived in South Africa for a while but met an unfortunate end when it was crashed. Whatever happened to the remains aren't known.
Ah, I think you're right. Honestly, for me personally, and alloy body alone doesn't change anything about a car...but I know I'm probably in the minority there. Anyway, I agree with Dave that practically speaking it's worth whatever someone is willing to pay for it....just not to me.
