I agree Gustav, however, I've narrowed it down specifically-- at least, so far-- to the air vents for the brake ventilation (i think that's what they are... located at lower corners of the rear bumper). To me, the slots are kind of crude for the rest of the car's character. As soon as I saw them I thought "that looks like something Techart would design." Not that Techart is a horrible designer... I can appreciate some of their stuff. But the Ruf has always be the quintessential "Wolf in sheep's clothing."Gustav said:I am not too sure of the car from behind. It looks a bit too extreme.
