Apparently used to race against 935s, Beta Montecarlos and 512BBs in endurance races back in the 70s... Not an overly competitive car, which is probably why you haven't seen that before.
I assume that the only "stock" bodypart left on it is the door-top form, as all the other stuff seems to be add-ons to make the car a "racer" but I cant even recall a car with such a top form...
as tou said "pretty danged close"... that CANT be a lotus spirit, RIGHT?
aaah, really? hell. thar one was a shot in the air. had never seen one before. it looks... erm... odd.
anyway, I think we should both go, as you did find the link to what it really was, I just said the name. lemme see what I can find.
