The Audi S6. Long considered the weakest of the super-sedans of the early to mid 1990s, the quattro has since created a legend of its own for the way it can shrug off miles that would bury other cars, the way it can handle supercar levels of power from a seemingly too-small displacement turbo motor, and the subdued fury with which it rolls down the road. Like the M5 and 500E, the S6 and it’s older brother S4 have presence that few other cars can achieve. Long one of our favorites at GCFSB, the S6 is also one of the best values currently in classic German motoring with most available for well under $10,000. Today, thanks to our reader John, we have a roundup of S6s in various states of tune and condition as well as color – which would be your choice?
