I am a Porsche guy through and through, I wanted a Cayenne S but couldnt justify the price once I got in the X5M. I already had a X5 4.8is and loved it but the X5M performs better, And is MUCH less than a Cayenne TT. I couldnt get Porsche to move ONE inch on price. I got a LOADED 2011 X5M for a song. Case closed. I like it so much I drive it more than my 2009 911 S PDK!!!
