Has anyone used German wool square weave carpet in their interior? I'd be curious to see some photos if anyone has some. I know it's not technically "correct" for these cars but it was stock in Porsches and VW's from that era. The 319 Black has just enough mottling in it that I think it would look very cool against black leather seats and leather trans tunnel cover.
I've read warnings against using wool if there's ever a chance of it getting wet, as your car will smell like a wet dog forever, but from May through October there's basically zero chance of rain around here so I'm not terribly worried about that.
