I leased a 2011 base Boxster about 2 months ago with PDK. When I asked about the 2012 I too was told that
there would be no significant changes until 2013. The lease program was very inviting on the 2011 models and
I would think there are still some available.
The car is a joy to drive or AIM as those who are manual devotees would say.
Good luck with your search.
