If you look up values right now, they will be higher than they have ever been. Value is going to be determined by what specific model it is more than they year. If it isn't in running condition (meaning that you can't get the engine to at least turn over and fire), then I would go into it assuming it needed an engine and only value it as a rolling chasis. I've already experienced the "it only needs a starter" headache personally and refuse to ever have that experience again.
Tires should be obvious with a visual inspection - wouldn't bother me as I usually would prefer a different one than on it anyway.
Battery - should be able to confirm with a jump pack, or jumper cables to get the engine to turn over, so minimal issue.
Fuel pump - a bit tricky here, but if it will fire on ether I would be more comfortable going ahead. If you can't get it to fire it could be any number of issues from very minor to very expensive.
You have to ask yourself, if it was something cheap and easy why didn't he just fix it (or at least bandaid it) and sell it off?
Also, how long has it been sitting? Possibility that mice got into it if it's been sitting long? How well does your buddy maintain his other things?
