it was made in the mid 80's the idea was after the race car the tyrell 6 wheeler it uses Cadilac V8 ...but does anybody know whats happen to this proto type
I remember seeing that picture in a book called Awesome Automobiles, or Supercars, or something like that. It is the Panther 6, and I think the production was something like 3 or 4. I owned the book in 1985, definately pre-Photoshop.
