No, mostly pretty wide of the mark so far but that's also kinda why I chose it, it's a misleading one
Ah just realised it was a one-off, though road registered. I can give the answer if this seems unfair, or give further clues. It's a variation of a popular model rather than some totally obscure prototype.
EDIT: No, scratch that, I'll say Frua Dodge Challenger Special.
If it is a one-off, then the round will not count, but it is a very, very nice and cool car.
I had not learned of its existence if it hadn't been brought up here.
