I agree with RC.

The Cayenne makes more sense with kids and if you need luggage space. Also it will be 10-20% cheaper... My 04 CTT has so much torque it already smokes almost everything that's out there... I can't imagine what the FL TT will be...

The only competition will be the X5M (X6M too small?). I hope Porsche offers a more road oriented car. Basically the opposite as now: one off road Cayenne S equivalent, and 5 road oriented models (base S TT TTS diesel)
