I wanted a Cayenne S and Porsche wouldnt talk to me even after 4 911's.
So I got a X5M for MSRP-$20K Got a 2011. I would FIRST look for a new 2011,
THEN go for a new one. I have looked and looked and stared at mine. I am a scientist
and this thing is built like a tank. Its very well engineered. Its my SECOND X5 and I sold
my 4.8iS to my son. For Cayenne S money you get the top of the line BMW model that beats the Porsche Cayenne TT in all categories.
