Bought this car in 2008 and currently km reading is 135000 and never gave me any serious issues but wear and tear replacement parts.Quattro is one of the best AWD systems in the world and prove it ability on snow covered roads and icy conditions.I drove roads with ease while ultra expensive SUV had a hard time ,either got stuck or was sliding everywhere.Interior its well designed and exterior wise its subjective but I like it.Comfortable sedan but BMW has a more smoother ride.Not really sporty unless you get it chipped and gas wise it isnt that great.Overall a great luxury car.
