 I was so excited to get one of the first 4.8i's in production (November 2006) to the point that I never considered that the car would be anything but better than my old 2003 4.4. As of late April 2007 I'd take back my old 4.4 in a second. The new X5 is a pig. Much slower, less comfortable (the sport edition seats are incredibly uncomfortable)things like my cell phone can't charge when the car is off,and that unbelievibly annoying seat belt alarm (you can't put groceries on the passenger front seat as an example) makes really angry at BMW.  And yes I will sell it shortly.
