welcome aboard
your looking for an 80's boat with no rot. wont happen. even an 80's aluminum (what jb referenced as a tin boat) would have had the transom rot out.
nearly every 80's fiberglass boat, and most of the 90's will have had rot already. By nearly every, I mean 999,985 out of 1 million.
your best bet is the newest aluminum boat you can buy. if you are looking for a correct craft specifically, there are three types of correct craft. those that need full restoration, those that were just restored, and those that were meticulously maintained and wiped down with a diaper and stored in-doors.
Good luck in your search.
