Well on the early one's the jA is A basic Box and the jx has the Xtras, my red one was a super zuk as some call it with chrome bumpers and other stuff that each dealer would order from a book and spruce it up as they pleased, so most of the sammies were all diffrent, but for the most part the jx has better seats and door pannels and plastics covers on things, decals, etc.
