John, PSM3:From what I understand the intermediate shaft was an issue on some cars....and the real main seal...RMS....while I am confident that not all cars had these issues...several that I was going to buys used from the dealer ended up having RMS....this was a 2005 911 and a 2006 CS....on the other hand the 2007CS I purchased had a good seal...confirmed when they dropped the transmission to solve a clutch issue....so I am hopeful that all these issues were solved on Gen 2 cars/with the new engine....
Maybe PDK makes up some of the difference, but 6-speed against 6-speed, it's not even close. There's no mistaking one for the other in terms of acceleration.The salesman told me that the performance of a Gen II 2.9 is almost as good as the Gen I 3.4. Due to the increased HP and upgraded transmission (PDK).
I went through this same process for a number of months and last week bought the 2009 2.9. I am more than pleased with my choice. I had great concern that I would be disapointed that I didn't have the additional power of the S. However having spent a few days with the non-S it has plenty for public highways-----and that's not even reving into the powerband prior to break in. I would look around for a better deal that the $48,900 loaner. Mine was a new no miles with Xenons, auto climate, bluetooth, ipod interface, floormats and heated seats for $41,900.My choice on a Gen I vs Gen II car has become quite apparent with two Caymans under consideration.
2007 Cayman S: Preferred Package Plus, auto climate, 16k miles, warranty ends Jan 2012, not CPO, one owner car. $39,900 asking (private owner).
2009 Cayman 2.9: 6k miles, CPO, warranty ends 8/2015, loaner car, no Xenons. No auto climate. $48,900 asking (dealer).
I want Xenons, but understand even the halogens are probably light years better than my old '98 BMW M3.
