For your year, in US market, the sports do not have a rear spoiler, and they do not have auto climate control, they do not have painted mirrors, they do not have 2nd row console, they do not have fog lights, there are some more I am forgetting...(shrug)
Grand Touring options were leather, heated seats, heated mirrors, xenon headlights, again, there are some others that I can't recall off the top of my head.
