If you are a pro bodyman then, yes, rust you can fix.
If you're a guy who can spin wrenches then pretty much everything else is easy except fixing a ZF. Since they are mostly pretty solid, major rust is your big enemy. And, unless you ARE a bodyman, it will soak all your time, money and energy just getting your car solid enough to be a beginning point. Just read the horror stories on this forum from guys who found out the hard way.
There seem to be a lot of reasonable looking cars for mid $30s and if that is too much, I suggest holding off and saving more until you can avoid buying a $20K car that will cost you another $20K to be a $30K car. Just my 2ยข. Have fun with the search!
