A 4 door M3 is a nice little thing to add to the positives of getting a M3 if you've got a wife who thinks it stupid for you to get a couple when you got a kid. I agree though, for me a 4 door M should be a M5....because, well because it is, or has been in the past, the sexiest mofo with 4 doors on the road. Even with it's flaws the current M5 is better then a new 4 door M3 if your talking about sedans...I mean come on.
