My friend has black E60 and he scratches his head every time it rains because the car looks so ugly after even a little bit of dirt/dust has collected on the rain drops and dries up. My Arctic E90 can last for a week or two of continuous raining without me worrying so much about how it looks because dirt doesnt show as much on that color. If you have plenty of time to clean your car then maintining a black car could be worth the extra effort, but for someone like me who has to work long hours and spend time with my wife, go to the gym and has other interests, Arctic is hard to beat. But that's just me
