im an ex audi rs4 owner as u see on my pic on my reply... im going to get a saloon rs4 in white soon haha love the sound of the v8 the rumble you get you can feel it going down ur spines.... so audi for win i drove my cousin 09 reg M3 yes its powerful but out of control just like the C63 goes everywhere lol... -worship
I am a beemer guy. But I will choose RS4 over m3. I drove the m3 and I think the shifting is not smooth.
m3 vs. S4 hp: 414 vs. 354 transmission: smg/manual vs. manual I think the m3 should be compared to the s5...since they're both coupes. If you compare m3 sedan and s4, i'd say the s4 has a better overall design. The m3 coupe and s5 are pretty evenly matched in terms of style, but m3 still has better handling and hp.
I'd prob pick the RS4 over the M3....Reason being the E36 M3 was a very agressive looking butch car...IMO the latest M3 looks a bit reserved....The RS4, on the other hand, has the same agressive styling as the previous E36 M3
