My mates wife has a 2005 S4 wagon, was mint for about a couple of years but has had constant issues with it the last 9 months or so, parts are expensive, they cant wait to get rid of it.
And another mate has a 2001 S4 wagon, V6 twin turbo. Bought it off an old guy and has a full service history with Continentals cars, he\'s had for about a year or so and has had to replace a whole lot of sensors cause it was running like crap, has started playing up again and now turbos are leaking oil every where.
