I'm considering switching up from my 2013, which is perfect, to a low mileage 2016 or new 17. From what I can find, there are very few changes, but there certainly must be some. I know the grill changed at 2014, as well as the interior retractable display which now stays up. Anything else? Any suggestions or recommendations? Am I foolish to change up? I understand this is the last year for the CT, and that is part of it.
