Its funny hearing S197 guys say the new interior does nothing for them...I had an 05, 08, and now a 2013 (picking up my 15 GT Monday), and once I sat in the 15 I realized how cheap and horrible the S197 cabins were.
That's because the 05-09 interiors were truly awful. The premium 2010+ are not that bad of a place to be. The base model, yes, the premium, no.
The new car has better materials, but it's not life changing if you had a premium 2010+.
But even the 2005 premium interior was horrible...even when it was new.
