And to be honest, it will see as much off-road as the average Cayenne or Escalade will, ie none!
I agree that the GC SRT8 and the 2006 Escalade with 20" aren't meant to go off-road ... but nobody wants to take them there anyway.
The Porsche Cayenne, on the other hand, could show a thing or two to all the jeeps out there ... and the sounds it makes.

(I'm talking about off-roading capability here ... not looks, price, etc.) "It has the sex appeal of a camel with gingivitis!"
