A couple of other things:
2013 has integrated turn signals on the forward side of the rear view mirrors (on the SE trim, at least).
SE Sport Cloth Interior is no longer available.
Rear parking sensors are now an option on 2013 SE.
Interior trunk release was added (at least on SE and above).
Piano Black Grilles, Disc Brakes, and Fog Lights are only available on the SE with Appearance Package (and above).
