I've owned An X5 and two X3's so I definitely see both points of view. We are empty nesters so we don' t need a lot of room but definitely need more than our Clubman S. Like I said, my wife likes the looks of BMW wagons but I don't like any wagons so this is kind of a compromise. The Sdrive should actually get the same mileage as the wagon at 24/33 or very close. I can get it pretty well loaded up with M Sport and Ultimate pkg and more at $44k while the wagon would probably run $49-50k. It's a no brainier for me.
