S6 - RS6 Little Help Please

[DSLiverpool]

Im thinking of replacing my CLS55 with a 5.2 6 series but Im not sure of the diff between a S6 and a RS6 is one just an estate ?

Looking to get a 12 to 15 month old one but the RS6 seem to be a new model, I can only find one on the Audi site

Any advise appreciated, Im an Audi virgin

Thanks guys, the RS6 saloon is the way to go BUT not at £75k, I will keep an eye out for ex demos etc but I need to drive one to see if its the right car for me ........ that will be a task itself !

I have asked to test drive a RS6 with a view to buying a ex demo when available
