Q:Help me understand the differences between the two models please.

A:2014 and newer doesnt have a crystal neon light and only the 2013 one had the best shifter that has neon light around the top knob, I recommend getting the 2013 one that I sent you link to, it looks so much better at night otherwise it is the same shifter as 2014 and newer that doesnt have a neon light around the knob,

here is a link to the best shifter that was installed only on 2013 models,
