2013 is the facelift (ZF2) which is a small power boost to the engine and the electric assist moves from NiMh to lithium and hence more power from the motor. Also adds a S+ button for demand full electric assist when overtaking. Strong prices for those when I looked.
Prefaclift you have S, Sport then GT.
Atleast Sport is fine, you get multifunction wheel and the decent stereo with subwoofer, GT adds a good amount. Ie Xenon, leather, pano roof although the extra weight and hence CO2 moves it a tax band in some cases.
Personally I always liked the dynamic kit on them aswell which is a honda accessories add on so not really trim specific- this Gives the carbon look side trim and rear bumper with mesh in, choose pearl white colour add a set of 20mm rear spacers and you have a really smart looking car, then throw in an Apple CarPlay headunit and you are laughing.
this is spot on other than mileage concern for some:

Just looking now seems prices have slightly climbed over the last year.
