They made the compact Cherokee from 1984 thru 2001 and the Sport was only a trim package in certain years so no big differences otherwise. There is LOTS of support in the aftermarket and plenty of knowledgeable folks on several Jeep forums. As Ed stated, as long as it is a 4WD model it will tow 4-down perfectly.
I have an old 1990 Cherokee Limited model as a toad that I found on Craigslist. It is a 4WD with Auto and came with the tow brackets and a towbar so it was a perfect find for me. Being as old as it is I had to do some minor fixes but it is a solid and fun vehicle and tows perfectly behind my old gasser. Sorry, but I am NOT selling it. You'll have to find your own!
