This is my wife's car, and she would call it excellent in every way. I, however would have some very minor reservations. We have owned this car a year now and it has been nearly perfect with no problems in 14k miles. It runs great, drives great, and in my opinion, is one of the best looking cars around.
If I were to change anything, it could do with a little less road noise. You can tell when the highway goes from asphalt to concrete by the sound and feel through the steering wheel. I understand road feel is a good thing, but I don't need to hear it as well.
I wish it could attain the same mpg as our old 4 cylinder coupe, but you will have that trade off for the wonderful power of the V6!
The gas pedal :)
Appearance (I am worried the wife will rub the paint off she washes it so often)
Traction control on slick roads. (Wyoming winters)
Less road noise (Apparently the 2013 is better) Simpler center controls for the stereo/cd/xm/climate control. (I still don't know what every one of those buttons is for)
