I did a M3 driver training day around philip island in brand new (4,000ks old) m3's... awesome car, so nice, well balanced.. it certainly doesn't put you back in your seat and doesn't 'feel' quick but thats because it's so smooth. a quick check of the speedo and i then realised i was going fast.
I'd have(want) one as a daily, but not as a track car, can't beat a well sorted out GTR on the track.
