Black, black and black!
Black exterior color is very important to me. It is my theme! :giggle Exterior color is a detail you can see first before anything, so in a way, if the car isn't black, I probably won't buy it. All the small details on BBR Enzo doesn't do me any good if the first thing I see isn't black on the exterior!
But then, there are exception like racing livery, etc.... :lol
