This is making me smile...
I just made the descision to swap my E46 M3 SMG (5 years old) for an RS4.
I pick up my RS4 on Friday
To be honest for the average person who doesn't do track days, doesn't drive at 10/10ths the whole time, tail out drifting etc.. etc.. they are both great cars.
I think the interior of the RS is significantly better than the M3's but performance and handling are very close (based on a test drive only so far) under normal driving conditions.
I chose not to go for another BMW because I just don't like the new flame surface styling. I really don't like the new shape coupe it just doesn't work for me.
While I was looking for a replacement I tried. (need 4 seats)
RS4 - loved it
S5 - very pleasant - lots of toys - just not special
M3 CS - great car, not different enough to my M and not as nice inside as the Rs
VXR8 - great engine nasty auto box wind noise low quality build
335I new shape coupe - hate the look, don't like the interior, not special
Of course the proof is in the eating so maybe I will change my mind once I have owned the RS4 for a while
Cheers
