Love it - best one yet
 i've have six 3 series and one x4.   the x3 m40i is the best one yet.   put this thing in sport mode and hold on.   it's quick and has a fantastic exhaust sound.   i've had it over 3 months and it still brings a smile to my face every time i drive it.   one thing.   if you don't get enhanced bluetooth, you can't get apple play.  keep that in mind if you special order it.
