So as some of you may have read, I am looking into buying an A4 Avant TDI B5. In standard form i don't think its a great looking car, but with the S4 kit it totally changes the presence of the car. Fitting the S4 kit would be my first change, so i'm wondering what sort of money they fetch and how often they are for sale? No fiberglass copies! This example I think is stunning.
