I'd check it out then. If it's solid and will do what you want, then there you go. O/T headers are very plentiful used if you're looking at a tight budget.
The main key is if it's solid. If there's no delam, and the stringers and transom look good, and the interior is clean enough to live with, and the price is right, it could be a good boat for you.
65 isn't out of the realm of most boats like that. You may have to put some money into the engine depending on how stock it is.
