Subaru 2007 or subaru 2011?

I finallly got the money for a wrx and i found a really good deal on a 2011 for a reasonable cost becuase of certain and easy fix conditions. Whats better a 2007 or 2011 wrx and are there any aftermarket parts for the 2011 including a body kit? i love both body styles of the cars so im not sure. I belive the new wrx has a an increase in horsepower too.
