What other special colors are out there? I have the "black cars", TVR speed 12, 2CV, solid color Ford GTs. I checked the other threads but didn't see a straight forward list. Is there anything cool to look for?
I'm pretty sure there are some of the manufacturer's races where you win cars in special colors, though the car is the same. The one's I can remember right now are the Toyota Yaris, the Triumph Spitfire and I think one of the Isuzus.
Edit: Here's a list of all the special color cars, how to get them, and the colors that I can remember:
