This 2006 replaced my 2004 turbo. Strangely, it is not as peppy in that the tranny does not adapt quickly enough for your spirited driving mood. This prompted me to put it on an all wheel Dino and it is putting out on the first pull but suffers from heat sink on the second and third pull. My 2004 lost the heating pipes and the Cardon shaft along the way to 100,000 miles where it loss the fuel pumps. During that span I did two brake jobs, replacing rotors both times. My 2006 six had 60,000 when I bought it and after 20.000, I have had zero repair cost.
I love the Cayenne's crisp handling and exterior styling. The flexibility of the interior and the supple leather and everything is just such a great combination. It really helps to get to work in the morning when I'm in a rush. Excellent job Porsche.
