If you're stuck on getting one with a 4.0 I would get an xj cherokee. Lots of info on them here. I would opt for a 97-01 preferably a 97-99.
On a side note having a suv and being in high school you'll be stuck driving most of the time cause everyone can pile in it. Although you can put the back seats down and sleep in it as well. I had an 87 4runner in high school and can speak from experience.
2001 amber fire cherokee sport 4x4, 2 in lift, 30x9.50 generals, 174 ion wheels, pretty much stock.
