Take it from a guy that works at a Honda dealer and has seen the 13 Si up close and personal inside and out, the 12 is overall better. I handle the accessories department at my dealer and the added chrome and fake carbon fiber don't help this car at all. Plus that wing ruins the sporty lines of the Sedan. Sure you get a back up camera, but it's a civic. Who the heck under the age of 45 needs a back up camera in a Civic Si? I knew all about the changes on the 13 before I purchased mine and decided the interest rate and low price was the better deal. Glad I chose the 12.. Also, for any sedan owners considering "trading up" the passenger side of the car is smaller due to the dash protruding out further.
