There is no way I would do that with a bike that old. The fork and rear shock are probably both almost obsolete by now and would cost a ton to replace. It may have been worth a lot when the guy bought it but that was years ago. Mass produced mountian bikes, unless they are something unique, really don't hold value well at all. Also it looks like an 02 I don't think they made one in 03. May have cost 1500$ new.
