There’s just something undeniably sexy about a dirty Porsche. It’s the kind of thing that makes collectors wince and the eyes of concourse judges moisten in agony. It makes me smile. Take the 911 SC in the photo above, for example. The car participated in this year’s iteration of the 2009 Rally Costa Brava Historic – a showcase of vintage tin getting down and dirty. You can almost hear that flat-six screaming through the turn. Sigh. [Source: IEDEI]
