Differences from 2013 to 2014 are... inexistant. Mostly tweaks, nothing you might notice if you don't look for them. 2015s have a few new nooks and crannies (default sharkfin, revised suspension bolts and struts, new colors, nothing earth shattering or that changes the car dramatically). The 2014 is basically a later produced 2013. Less off-the-lot issues, pretty much.
At this point, it's your choice on newer but sticker price or 2014 and better price.
Either way, whenever you come back, we'll welcome you once again
