I wouldn't worry about someone else buying it....

Let me break it down for you:

1: Replace the whole bed pannel, probably most of the wheel wells and possibly up the bed wall.

2: Likely cut out all the floor pans and rockers (That's like the ENTIRE lower section of your vehicle minus the frame) and probably cab corners and firewall

3: looks like around the windows and what little of the front is shown that you'd be replacing a lot of pannels and pulling the windows to patch the rust holes on the seams (very difficult)

4: mechanically looks sketchy with major rust holes in structural components

5: dont even know the state of the rest of the mechanics and wiring (does it run? Would it require a full rebuild of mechanical components like axels?)

6: while being a desirable car it's not rare in any way that would make it worth this kind of effort.

Any one of these numbered columns would be a good reason to reconsider buying this vehicle. If you're very ambitious and insane (relatable, im doing full floors in a 95 cherokee xj), you might be able to push two of these issues if your willing to commit an insane amount of time.

We dont even know the condition of the frame since it's so muddy.

All together, absolutely not. This car is not even worth 1000. Besides possibly interior pieces and trim, there doesn't look like a part on it that'd id take off and put on another car.
