look for rust where the front doors hinge from! don't want structural damage now.
it's normal for some rust to be under the spare tire area, same goes for battery location, and rear mudflap location.
is the windshield cracked? because you're not finding another one! and if you do, they go for $300+ just for the glass, plus shipping, plus installation.
these engines are very bullet proof, just make sure the crank turns over to make sure it's not seized up and you should be fine.
post pictures! i would love to see another survivor.
the plastic in the cargo area is usually gone or falling apart, same goes for the dash, there's probably less than 10 that don't have cracks across the country lol.
if it's a manual, look at the pedal box for any cracks or separation.
not sure what else to really say without pictures, alot of these first gens leak water in, either through pin holes in the cowl that let water fall through into the passenger side floor, or in the top corners of the windshield seam.
