Need a little help. The 2013 rs6 is gone and got replaced by my rs4 b7, but the itch for the rs6 is still strong so i really want to own the rs6 c6.

The question is what year model should i go for? Is there any big difference on the 2008 model to the 2011 model ect ? Since i got a good offer on a sepang blue 2008 model, but also looking at and 2011 plus model. Is the extra cash worth it?
Thanks
