Stealth Speed

[MudSurfer]

Not a Surf thing I know, but I'm looking to replace my other car in the next couple of months, I have currently got a 2 year old Volvo S60 D5 - great car, but not quite the stealthy speed mobile I used to have - had an uprated T5R estate, and a chipped and fiddled with S80 T6 (355bhp) and now I'm looking for something else that is FAST, but doesn't say so all over the place - no silly spoilers etc - so, I have started looking at an Audi RS6 - or an S6 - but can't find any S6s on the Audi site - lots of RS6s (I assume this is due to license losses.. ) Any other suggestions?

The RS6 is seriously quick. My mate (05 Prodrive Impreza STi) was comprehensively buried by one a few months back (in a straight line admittedly)

I got passed by an RS6 Plus a while back - I saw it behind me for a few mins, then there was an almighty roar and he was still behind me, then a couple of seconds later he was in front of the car 5 cars ahead of me.......as Andy Pipkin says...I want that one!
