How well does the C7 age?
 

I took delivery of a 2.0TDi S-Line yesterday and was wondering how well this line of A6's ages over time?

It's only been out since late 2011, but what do those who have had theirs for a while or clocked up big mileage have to say?

Does the flawless and legendary Audi interior stand the test of time re: wear and tear, noises, rattles, creaks etc.?
