That's a clean boat, been for sale for a few months I believe. All the black that thing is going to get super hot. I don't know about 80, but if he has put as much money as he did into looks I'd assume he as done some work to the motor too. Those are all around good boats, solid and well used for the river.
Check normal stuff like the bulk head, any wood rot, or cracks in the paint (because I'm pretty sure it's not the original gel coat), others will chime in with more things.
