Mental cars. My bro's mate has one (S reg) The only carbon I know of tho is the interior trim panels (on dash, doors etc) is carbon fibre, instead of walnut-looking plastic in lesser models

But seriously mental cars. He (my bor's mate) has modded his with uprated suspension/brakes/rims, has the RS4 turbo's and intercoolers, and an exhaust and re-map from AMD, and whilst it has a bad misfire problem, it made over 400 lb/ft on the rollers (can't remember the bhp figure's) AMD estimate when it is cured and sorted, it should run over 400bhp (going for 420 IIRC) and nearer to 500lb/ft

But I really want a BMW 330 TD mapped by Stu to smoke him in - so Stu tells me anyway

Build quality and driveability of the Audi S4 is just SUPERB tho. Like TOny said - bullit proof! I was passenger in it on last years trip to Donny and whilst it felt like we was doing 70mph, we were actually doing 150mph
