IMHP, if you wish to spend the extra difference between a stock M3 and a SPecial Edition M3, by the normal one and do the upgrades yourself if its about speed. An Akropovic Exhaust and an Activ SC will do you a lot of good. And if you want exclusivity, who else can have a car like one that you've pieced together. That's just my opinion.
