a bit OT:
Sad thing about a white car (which my BMW is) is that no matter what you do, it's a color that never really shines well, and has no real 'impact' on the look, like dark colors...Pretty much all other colors can be made to look great with good detailing, compared with white.
This discourages me from giving my bimmer the detaiiling-love it really deserves..i just do what's needed for protection, and that's it. Other BMW owners love my Alpine White BMW for its color though.
Just like with my Tbird, i gave priority to other aspects (low miles, relatively hard model to find, packages, condition) etc over getting a dark color, which I know would look better....
Only in night time photos can one admire the look of a white car, when it's well-detailed...
