In my opinion, too many colours for a car. I'm really special with colours, and I don't like black roofs or bonnets, as it seems the cheap way of getinng some carbon fiber lookalike, like M3's roof or any carbon fiber bonnets.
That's just my opinion, as I have a nimbus grey 197 with white speedlines, and they are not to everyones taste, but in your car I would really love it with just white wheels, It would look amazing.
