I used to have an 03 e46 M3 and loved it....this on is even more fun. Exhaust is a tad quiet. I cut the resonators from the 5 and it made a dramatic difference. I am contemplating removing them from the roadster but I have a feeling that my wife would object as it "her car" LOL.
Congrats! I've driven these a lot and they are a lot of fun. Great choice to pick this over a Boxster S. The Boxter is a nice car, but very little comes standard and they are far more expensive than M roadsters from similar years.
