Like people have been saying...i'd rather have the less powerful M3 and pocket the change in difference.
Mercedes has always been going down the route of big displacement V8 and V12s with some of their AMG motors being supercharged. BMW has usually stuck to smaller displacement naturally aspirated motors (until recently).
Hell...if we're taking about that kind of money, isn't that near Porsche Turbo money? Maybe I'd get that instead.
