I had the 2.8v6 one of these years back.  
i bought on a whim mostly because the missus told me i wasnt allowed.  Loved the look of the car, but that handling OMG.  i took it around Oschersleben motorsport arena which is quite a technical track and it was horrendous. 
It also cost me an arm and a leg in maintenance.  I bought it on an M plate with full audi service history and 80k miles for£1500.  boxes of receipts and immaculate inside and out.
however iirc i had to replace one top mount, an engine mount a shock absorber, a fair few bushes, the cam belt something to do with the gear box, service it and replace the tyres.  I also had a small blow in a the downpipe which was over 900 euro from an audi dealership as independants couldnt get hold of one.
So i sold it in the end having spent more in one year on repairs and maintenance than i did on the car in the first place.  Never again will i buy a car thats 12 years old again.  Never considered that was about the age that all the bushes etc start to give in
I would love to get the S2 though
