Got an X2 loaner this morning. My car is a 2015 335xi.
First, I really like the ambient lighting choices that show up even in daylight. Next, I really like the shifter which actually changes position when you shift it, (like ordinary cars always did). My car always goes back to the neutral position so it's hard to know what you're shifted into without looking at the indicator lights.
It has a nice ride.

On the downside are the rear headrests that obliterate the rear window view (Volvo has a button that flops down the rear headrests....great feature), the need to have the rear wiper always on in rain to see anything back there. Couldn't figure out how to shut off that pass side curb mirror when backing. My comfy seat position made the wheel and armrests too high. And the iDrive has much fewer functions and choices than the 335xi. NAV screen is miniature. Maybe I need to drive an X3!
