I called Fox Valley Motorcars about that F1. The guy who knows the car (knows quite about that particular car in fact) was not in today... they told me to call back tomorrow, which I will do. So you guys'll find out tomorrow.
Oh, Btw, click the link below if you'd like to see two of the new colors in-game... I've finished them all, but I'm too lazy to take a bunch of screenshots right now.
