I'm sorry if this has been discussed before, but I was wondering exactly why members of this board bought the RS6, and why I should by it, over say, the E39 M5.
Can you tell me any noticable advantages it has over the BMW. I'm mostly interested in performance, as you can't go wrong with either of these cars luxury. I havn't yet driven an RS model, but I can say the M5 doesn't dissapoint.
Thanks for the thoughts,
Cheers
