I found white easy to look after...sure it shows the mud and road grime...but you can touch in stone chips invisibly...car door door pings don't stand out like they do on dark or red cars...you don't have to worry about polishing it so much as the shine does not show so much. I had a white 318i and a white Orion (no laughing..it was a long time ago and it was an injection Ghia (XR3i with a boot!)) and quite fancy a white Giulia QF with dark wheels and yellow calipers...like that's ever going to happen!
There you go! One you can call your very own!
