[s-cars] RS6 Colorado anyone?

[Frank Amoroso]

There was at least one RS6 in the states not too long ago, making its
way through along with B6 S4 V8, B4 RS4 w/ v8tt motor in it etc.. These
were certainly cars with dealer plates and they moved on to AZ after
stopping in CO.

I bet what you saw (not sure) was an A6 4.2 V8 with RS (from readily
available RS4 badge) and 6 (from S6 or A6 badges) put together.
