 Nothing compares. A fantastic driving experience.  This car is truly the ultimate driving machine.  Picked up the BMW i50 X6 and have been totally satisfied.  Traded in a 2011 Porsche Cayenne S!  No comparison this time the BMW IS better than the Porsche (Couldn't say that about my 911 vs M5).  You will be happy with your decision if you purchase one of these.
