Have owned my 2005 Cayenne S for seven months now and could not be happier. I have had absolutely no problems except that the navigation system stopped working right after purchase, the dealer replaced entire PCM system. It is the best handling vehicle that I have ever owned, although ride is a little stiff for touring. I wish I got the adjustable air suspenson option. The V8 engine is fabulous, smooth, and has excellent acceration. It gets acceptable gas mileage. The PCM system with navigation, satellite radio, and Bose sound system are all top notch, although the navigation system is more difficult to use than Acura system. I am happy that I purchased mine with the smooth leather and burl wood options. It has beautiful fit and finish. All in all - this is an excellent vehicle!
Handling, power, and PCM system.
Simplify folding of rear seats. Include auto-dimming rear view mirror as standard equipment. Make rear passenger seatbacks adjustable. Give the navigation system touch-screen operability.
