I would find a qualified surveyor in the area to look at the boat if you are serious and ready to pull the trigger. Just a quick look will only tell you of the cosmetic condition. Many clean / new looking boats have hidden / reel serious problems such as delaminated or wet stringers etc especially in a wave crushing boat. I have bought and sold a number of boats and it's money well spent.
Go to this site and ask who is recommended in the area.
