After side-to-side comparo with CPO E53 it was no question what the Missus wanted.
Love the sport option, wife especially loves the sport seats as she has no back/sciatic nerve problems.
Handling is incredible for an SUV. Even for a car. If you haven't tracked one I highly encourage it. Brakes no slouch either.
Great road trip vehicle. Last summer we drove to NorCal by way of San Antone and returned on I-40. Pure driving pleasure and 21/22mpg, except in West Texas with that 80mph speed limit that I might or might to have exceeded by 10-14 mph.
Great off-road too. We drove the test course in SC and were amazed. We'll probably never use it, but it is there for those who do. You cannot believe the lateral grade it will hold w/o rollong over. Not just a pretty face.
Size was surprise to us when we returned home and found it would not fit in the 99 Jeep GC Ltd's spot in the garage. It looks and drives smaller than it is.
Hate iDrive. Am told it has improved but it takes two (one to drive, one to iDrive) of us to operate it on the move.
Would have loved to V8, but between cost and mileage it was not much choice.
Hate the manual shifter - I keep getting it backwards and having to check the shifter in order to go up/down. Seems to me like you should push to go up and pull to downshift.
Wife has no problem with shifter, but I have trouble park/nuetral/forward/reversing.
I don't really like the starter button. Just one more motion to get 'er fired up or turned off.
Our first BMW and we are probably hooked.
Wife is thrilled with it (it's really hers) so I am thrilled. Mama ain't happy ain't nobody happy.

And did I mention the handling!!!
