With the sport package, I believe that you'll get the dark headliner which looks great. I can't imagine having a creme colored headliner. Also, the exterior of the car will be trimmed out in black rather than chrome. I really like the dark trim which gives it a custom look. I think it is called shadowline trim. In my opinion, this is mandatory with black and the space grey for a cool look. I am sure there are other things you'll get with the sport package.
