I'm not sure if I've seen one or just an A3 with a badge. Can't say it jumped out at me enough to be bothered to divine the difference so I suspect the latter.
to me, the RS series has totally lost its special feel.
The RS2 was almost mythical, as was the original RS4 & RS6, the new versions of those were also fantastic but from the RS5 forwards they are just halo brands and not super cpecial anymore
I've seen one on the back of a loader I think. Never on the road though, would it stand out that much? I can't even remember what one looks like now :S which is weird, because I can remember exactly what the M1 looks like!
I saw one in Johannesburg in white. Not sure if there is more cosmetic difference over a standard S3 - other than the black alloys with the red highlights as previously mentioned.
A mate of mine has one on order (he put his name down when they frist announced it) and he's recently been told it won't be delivered until Jnauary next year at the earliest! I suspect the reason few have been seen is because few have come into the country so far.
