You'll never get Sandman money for it without the tags so if you were to restore it would be as a replica basically. Someone might give you a bit extra for it as is if they need to reshell their Sandman ute, although usually the guys with a spare set of tags are the guys who try to get everything as cheap as possible.

In saying that, it's a good ute with good gear. Get what you can and buy a sedan or wagon to do up so you can take the family with you.
