I would wait, the price is kind of high for the specific model. My used 2005 X5 was only 10,000$ more with all of the options except: DSP, the annoying PDC, and Nav. The navigation is a waste( i would rather buy an aftermartket, or just a Garmin.) Oh yeah, and it also has 225 HP vs whatever 2003 and older have(i forgot)
