Wife brought home a Challenger

2016 they offer Plum Crazy, 2015 they offered Sublime but it's not available on 2016.

Talked to her again about Sublime, she thinks it's cool but maybe too much "in your face". I said I think that's the point!!! She also likes the gray which is the color of her rental. I'm wondering what are (if any) the changes between the 2015 and 2016 models?
