Hmm. Interesting. Inclined to agree with you. All wheel drive, fairly good looks, and pretty decent power.
I question whether it is truly an issue of lack of demand, an inability due to costs, or lack of touch with their customers, for Audi to bring the RS6 into NA.
I make the assumption of course that many, if not all of the NA folks on this thread were looking forward to buying the new RS6 if it were made available. I had my name down for the C6 which never came, and also now for the C7, which looks like it will also not make it.
Amazing in this age of globalization that we as enthusiasts have to resort to other brands to address shortsightedness on the part of the brand we all want to stay with.
