The M5 is definatly my "if i could have any sedan available right now at no cost" car 
too bad that by the time that i'd be able to afford one, they'll have something new
Yeah "M" mode opens up the throttle bodies more. The E46 M3 have the sport button whihc do the same thing and it's awesome the difference that button does.
