 This X5 has been great so far.  Had 26,500 miles on it fully loaded. Absolutely pristine condition inside and out.  Excellent driving on winding roads and certainly plenty of power for the freeways.  Gas mileage could be better so still getting used to that.  Only design flaw I find is the Navigation unit and its location for glare and the cup holders.  Both were rectified in the 2007 but getting this for $35K I consider a good deal versus pricing of new models.
