Black.
First and last black car I will probably ever own. Sexy when washed & waxed, but impossible to keep it clean longer than 24-48hrs (dunno)
I perfectly understand what you mean.
Despite my premise, until last month I had a black Peugeot 307SW. After two or three years of desperate fights against dust and dirt (I've been washing it once a week) I had to surrender to the fact it would never stay clean for more than 2 or 3 days. In the following 4 years I've been taking it easy...
Black still is one of my favourite color, but it was time to change.
