Thing is though Howard, the Cayenne whilst looking like the back end of a bus, is actually a really very capable car. Having had a bit of a 'play' on a private road with a Cayenne Turbo in the Clio I can comprehensively say that they corner rather well and stop like no other bus I've ever seen. I very nearly rear ended it at one point it bled the speed off that quickly.
Their purpose may just be for taking the kids to school in Surrey, but as far as all round AWD off roaders go, the Cayenne series in my eyes are pretty tasty - albeit in a way that only its mother can love.
