New Member, Southern California. Purchased a 2011 Certified Cayenne S with 29500 Miles, with a warranty expiration on June 2016. Gave my 911 after driving it for several years to my son in 2001, old age knee problems, meniscus tear tired of shifting. Bought a Corvette C5 in 2001 with AT, great vehicle very comfortable. I drove the CS to the mountains yesterday. Was not aware that I was travelling at 94 MPH in the freeway, smooth, great road holding, thoroughly impressed with the performance of this SUV. Got 17 MPG going up to an elevation of 5600 ft. Got 23.9 MPG on the way down.
