I personally could not move from a 2011+ to a pre-2011 model, more power or not. Opting for a new 2011 V6, I obviously could have purchased an older CS or Turbo for a similar price or much less. And while really do like the exterior of the previous gen Cayenne's, the interior just didn't cut it for me. I love the way the new Cayenne looks, inside and out. But, TEHO, I'm sure plenty of pre 2011 owners enjoy their Cayenne's as much I enjoy mine.

Good luck with your decision!
