ive driven 3 RS6's
and i nearly bought one last xmas
ther not all spec'd up the same
look for soft close doors,rear camera,keyless entry and start,tv,ami and any other goodies
the price is definitely spec orientated
and i share your passion for one now they are coming down in price
this is the one i would buy if it was a tad cheaper
