Mike,
didn't you already ask this question?:

the differences are in the additional packages that these models can come with:
Tech, Advanced Tech, Journey, and Premium (not offered in the sport model)
1. the sport is going to handle and ride a little differently, basically a little rougher (although for the sake of "improved" handling...plus, although some would argue they don't notice anything major, the sport comes with the RAS - rear active steering which is also supposed to help with handling too)
2. Styling differences - although the headlights can be modded to look like the sport, the interior trim can be changed to the aluminum, the sport body kit can be added (quite rare since they don't manufacture it any more), and the rims can also be switched as well. the stitching color isn't so easily changed unless the previous owner switched out the steering wheel and seats
