the price / value of something like that could vary a lot. the days of buying a $500 vehicle that was functional are long gone. you can sometimes get near that in scrap value alone on a vehicle. now figure in that it's a very common make and model truck, and you have a salvage value of quite a bit, because there will still be trucks of that style on the road for years to come. even on core value for some of the main parts - engine, transmission, transfer case - you've got something.
years back i bought a used high mileage company truck that was the same body style and it had the same door pin issue. as probably is the case with this one, it won't be able to be repaired perfectly, because they neglected to replace the bronze bushings and the pins when they should have, so the pins wore into the steel of the hinge. you can likely put new pins and bushings in now, but the holes in the hinge are likely worn larger than the bushing now.
the thing that would keep me wanting to offer on the lower end would be that it's bordering on 200k miles. alone that's not unheard of, but when you look at the driver's seat and the door pin issue, it's had an awful lot of start, stop, in and out use, just like any typical town truck would. if it was a salesman's or commuter's vehicle you wouldn't see the seat and door wear as bad at 200k miles. you can assume multiple operators who were just "on the job" and didn't really care about the condition of someone else's equipment.
if their estimate of $1500 is real, and not a load of bs, then there really isn't much to do. $1500 doesn't go far when it comes to repairs now. check brake and fuel lines for rust just to see what you are likely to have to do next. maybe used doors if you aren't fashion conscious. fix the floor properly and it probably wouldn't be too bad. assuming that there are enough interested parties that are interested, my guess is that it could go around $1000-$1500. is it worth that? well, hard to say, but check the stuff out there for sale in that price range. every now & then you'll find a diamond in the rough, but they are few & far between. to be honest, with a few repairs that truck is probably more sound that a lot of the ones i see on the roads here.
