Needs a LOT of work, at least in cleaning it up. And even then the price is too high.
The first thing I'd do before buying is see how the bucket seats are mounted. If he drilled new holes in the floor and stacked washers to do it I'd turn around and walk away. That mentality will have carried through the whole of the truck and fixing all of that would a big pain.
