Yeah, I agree--black gets dirty really fast but it looks amazing when clean. My car is Satin Silver Metallic...hard to tell when its dirty after rain except all the rain & dirt spots on the windows b/c of the tint I have...
Celica '00 Carbon Blue (Dark colors look cool but they are harder to keep clean!) I would have preferred it be silver.
I have a Toyota Supra and it's white. I like white since it's really hot here. My next car will either be pearl white or silver.
The exterior color of a car affects the interior temperature very little. Yes, black paint will absorb more energy, yada yada, but that heat stays on the outside, it does not really seep through to the interior.
