I have had this SUV for about 4 months. I was driving a Mercedes S550 AWD the last several years. I miss some of the creature comforts of the Mercedes and the smooth ride.It is simply more refined. The Cayenne is more responsive and a blast to drive. I am sell getting used to the profound differences of the two vehicles.
My "other car" is a 2014 911 Turbo S, and I have to say it's hard to pick which car is more fun to drive on an ordinary day. The Cayenne is so comfortable, but the V-8 in this (in Sport Mode) is just a beast. I'm not sure I'd pay the $$ for a new one, but I got this used with 14K miles...the CPO warranty takes me to 100K miles. Highly recommend it if you're looking for a sports car, but need the size/convenience of an SUV.
