I have to agree with Fred. $2K is a lot for a rusted 88'. Now if it has a new engine & tranny then it's maybe a little different but still, as he said having the rust repaired at a shop will probably run you close to or even more than the asking price for the truck.
On the other hand, the doors & tailgate are both bolt-on's and as such they & the front fenders are things you can replace yourself in the driveway using hand-tools. If you just have a shop weld some patch panels into the quarter panels and then sand it yourself & have it repainted by someplace like Maaco then the economics become a whole different thing. It just depends on how much of your own work you want to do and how much you're willing to learn about *doing* your own mechanical & body work. Get more info on the drivetrain, plenty of engines DO sound good at 145K but this is something that you need to probably get another 40K-50K out of. You'll be doing a lot of back-n-forth driving between home & school and the last thing you need is to blow a head gasket 6 months into owning it.
To be perfectly honest with you though a 93 Maxima is probably a much smarter choice for a college student. Unless you're familiar with doing your own work or you're willing to learn (and even if you ARE willing to learn, don't discount the cost of building up a good set of tools. Good tools AREN'T cheap and you need more than a ratchet & some screwdrivers to do your own work) then a Bronco can be an expensive toy to own. If you're reasonably close to home, have access to tools and assistance then sure the Bronco can be a great truck, especially if you decide to learn and rebuild it piece by piece, but I've seen more than a few people get into trouble making choices like this. Understand what you're getting into before jumping in with both feet. there's no shortage of people here willing to help out, but there's only so much that you can do over the internet

Go & take a second look, find out more about it and post what you find out. This may or may not be a good choice for you but there just isn't enough info right now.
