Im looking at two base model 987.2 Caymans. 2009 vs 2011, virtually identical mileage (50K), one owner cars with strong carfax reports on each. 09 is 2500 cheaper, after negotiating terms of both. 09 has couple extra features- heated seats and upgraded sound and bluetooth connectivity. My question is- What are the main differences between the two years and is the newer always better just because of age? Any input will be much appreciated.
