I love detailing my car but the Sapphire Metallic Black shows dust and damage. I have professional level tools for cleaning such as the speed adjustable porter cable buffer. If not for that I would have gone for white with tan/brown interior.

I used to detail cars when I was in high school and white was the easiest, black the hardest, but don't kid yourself silver is a pita as well.

If you want low maintenance get white.
