my dad used to have one, and they are really sick. but, we had to get rid of ours because it gets to a point where it costs so much money to maintain the car that you might as well sell it.
A kid at my school has one of these. I creamed my pants 5 times when his dad rolled up in it, puffin away at a cigar. His is outfitted for racing too, with nitrous in the trunk, 4pt seatbelts, roll cage, and subs in the backaseat; and looks just like that [same paint job, headlights, condition]. Id give a nut and a half for it, no question!
I would take one of each "S" version of the audis. My uncle has the 2006 S4 Avante( I love sport wagons) and it is madness. He is putting the components from the RS4 on it this summer. The blue is amazing.
