6 months and zero issues at all (never had this experience with prev. german cars purchased). Everything works well, surprised at how well it drives in snow (took it to Killington VT). If you drive carefully, easy to get 30/31 mpg on the highway (auto trans), but the moment you put some gusto in your driving and you hit 22 mpg very fast.
Great front seats, and very good trunk capacity with seats down (put in the back Queen bed head and foot boards + 40inch TV -- all with boxes. Very smooth auto trans, and great handling (I do not have sport package, but for me it suffices).
1) Rear seat armrest. 2) More trunk lining. 3) More compartments to store stuff. 4) iPod integration good, but should be standard, not optional. 5) 6 cd changer should be standard. 6) No more run flats, add a spare tire, old fashioned way is the best way.
