2009+ are a big improvement IMO. Faster, sharper looking, PDK.
A 981 is a pretty phenomenal car. They sound great and drive great. I got some seat time in one at the last PDS. Electric steering is both more reliable and better road feel than traditional power steering so try one before you discount it.
