No. There are some different trim versions like the Mopar 16 edition, and only slight changes with it. If you buy used, you might end up with non-stock options someone installed. That could be a plus or not for you. The only real difference is a couple more paint options with the 2017, and some "options" are now standard - the Limited Slip Differential (Anti-Spin), and the Rebel instrument cluster used to be options and so not every 2015/16 will have them.
