I'm not collecting EVERY car in every color. But I am collecting some of them. Old Ferraris, Lambos, Porsches and BMWs, as well as Renault R4 and R5s...and several others. So far I have about 800 cars, so lots of room in the garage for more still. It's just something fun to do and as such, I don't really want to know ahead of time what's potentially available in the game. I'd rather be surprised by a color I don't have lol. While it's true you can just paint cars whatever color you want, that doesn't really make things any easier unless you don't care about having the car in the previous color. You still have to have an example of the car you're willing to paint. Plus it doesn't account for the different interiors some of the cars have with different external colors.
