I had a red pontiac (never got dirty)
I've had 2 black cars (washed them every week).
I've had a gunmetal grey car (didn't have to wash it that often)
I now have amberline black (posh word for metallic burgundy) lovely, doesn't how up the dirt that much but it's the alloys that get me every time, so I wash it once a week (there's a 15 minute brush and spray jobbie in my local shell, you need 15 minutes on the monster).
