Evening fellow members! After my brother recently purchased the new RS4 Avant, it's got me wanting an Audi with a bit of punch.. I've got my eye on one on an 09 plate with fsh, and looks very well maintained. It has a miltek system, eibach springs with uprated dampers. RS4 brakes up front and an MRC stage 2 map. It has 110k miles (is this something to worry about?) Is the mech unit a common problem? As its a very costly fix. Also,does anyone recognise this car?
