Got to tell you I am impressed with the Cayenne. My sister road in it a couple of times and she liked it. She bought an Infiniti FX35 which is a nice vehicle -- I drove it 2 weeks back in July 2012 -- because the Cayenne was a bit too rich for her budget. If I was in need of an SUV I'd certainly consider one. I think I would prefer the gasoline powered model but the diesel model could make sense if one drove a lot of miles.
I have no complaints with the vehicle other than I have to give it back Friday AM and swap it for my Boxster. (Well, I could keep it but I'd have to fork over some money...)
A bit of Boxster content: My Boxster is once again water tight!
