My .02 is that I am not that impressed with the body work. The engine stats are awesome, but the new front end doesn't do it for me. I don't care for the monochromatic look (I don't like the M sport package either). For my money, the current front end with the aero kit looks better. But I would want what's under the hood. The interior is essentially stock except for the knee bolsters from the X6, the gauges, the headrests, and the steering wheel.

My guess is the facelifted X5's will have the 4.4 TT from the X6 as a replacement for the 4.8.
