I thought of the Vector as well. Also agree that a few cars have drawn upon styling cues....however, there were many wedge shaped prototypes over the years.
When I asked the question I placed the word "car" in quotes. I was using the word loosely as it was a kit car and not a production auto. It was deliberately developed as a copy of the Carabo.
BTW, Gerry Wiegart(sp) originally intended the Vector to use a 911-6 to power the car. IMO, one of the most interesting autos in recent history.
