Whats the difference?

What is the difference between a jeep cherokee sport and a jeep xj? :wtf:

All Cherokees are XJ's. Cherokees came in different equipment packages such as Sport, Country, ect.

XJ Pretty much means cherokee
ex: the jeep xj sport = the jeep cherokee sport

Thanks, thats what i thought, but i didn't want to seem like a retard
