3: Straw man argument. You already did American muscle, so clearly the RS6 had/has something you liked. My guess is that you thought it would be cool to have a relative "sleeper" of a not-too-pricey AWD German sedan that would kick butt and take names. My point is that a C7 S6 is a much better starting point for such a project.
4: All of that said, I understand the attraction of the RS6's low price of entry, flares and stance, and I wish you nothing but the best. I'll be watching this space for your progress.
