I previously leased a 4.4l X5 before my Infiniti and had to get rid of it due to all of the malfunctioning electronics. It was like driving a vehicle that was never tested off the line. The FX is far superior. It's faster, handles better at high speeds, and the electronics all work. Not to mention cheaper, too...
Satellite radio, Bose sound system (which kills the crappy Harmon Kardon system in the X5...to this day I won't buy Harmon Kardon again.) Bird's eye nav
Due to sportier handling, the ride can be a little rough and you really feel the road. A little less of this would be OK. Also there are some blind spots when driving.
