It would cost quite a bit to make it a nice original.
Vin Plate has been tampered with, not good even if original. Also, I believe it should be AG, not KG. What does the vin on the windshield post look like.
I don't see the 2 red horns in the fenderwell. Interior is nice except for dash cap and visors.
Paint chip, color and trim are issues. Is the S bumper original equipment?
I'd want to poke around the jack posts and the front suspension pan to check for rust.
