X35i or x50i?
Coming from the 4.8L V-8 in my 550i M-Sport I have to think that a six cylinder turbo isn't going to have the rumble I'm used to. I know the x50i is faster and sounds better but is it really worth the extra coin? I'm pretty sure Ill be going M-Sport as that really sets BMW's off even more than they already are. Go!
