Though they may not generate the gasps and pleasure groans of the RS models Craig and Andrew wrote up last week among enthusiasts outside of the brand, classic Audi fans in the U.S. still regard the original S4 and S6 one of the best models produced by the company. Indeed the S6 Avant has gained notoriety as a “Holy Grail” for fans of the marque here, as it offered the ultimate development of the C4 chassis and inline-5 coupled to analogue all-wheel drive offered in this market. Only a few hundred of these wagons made it here, increasing the mystique and desirability of the package. Both of today’s examples are presented in the defacto signature color of the C4, Emerald Green Mica (Smaragdgruen Pearl) with Ecru leather and both have been turned up a notch from stock. The first example has all the wizz-bang completed, while the second has been maintained and is ready for further upgrades. Which is the one you’d like?
