David, As well as I remember from "Stainless Steel Illusion" the windows were one of the main differences between the prototypes and the production models. Also, one of the prototypes had a Citroen 4 cylinder engine. The second prototype had the PRV. There were only two prototypes. I want to say that they had different style knee padding and had tan interiors. There are several pictures of them in "Stainless Steel Illusion."
