Why buy a used Audi S6 with Exchange and Mart?

Audi's 'S' series of cars occupy a narrow but well-defined niche. Not quite as focused as BMW M cars nor as powerful as the heaviest hitting AMG Mercedes models, they nevertheless offer serious performance with impeccable build quality. If you feel the need to ramp the intensity levels up a notch or two higher, Audi also offer the premium sports RS models but for most A6 executive saloon and estate buyers, the 'S' treatment was quite sufficient. The 340bhp S6 we look at here was created in late 1999 and was justly popular. As a result, there's no shortage of choice for used buyers.

About the Audi S6

The Audi S6 is in many ways the forgotten car in the executive express class. The BMW M5 is the car for the serious driver and the Mercedes E55 the default choice for the autobahn wafter but the Audi strikes a good value and well built compromise between the two. Despite the fact that it's been superseded by a newer shape car, the S6 still looks a class act.
