Meh. I'm underwhelmed as well. If they had put in a high-revving naturally aspirated M POWER engine I wouldn't care WHAT it looks like, but honestly this isn't worth the extra $9k USD. Bigger brakes, M differential, nifty suspension, rack and pinion steering... but same engine and body style. This isn't a new car, it's a fancied up 135i (as it has always been) and it's not the car for me.
But hey, to each his own. I'd be perfectly happy with an E46 M3
