Potential Buy this weekend, have a few questions

[brian_gem]

This would be my first boat purchase, so I'm a little nervous! I am eying a 1975 - 20ft potter. Boat appears to be in good condition, but I am aware of potential stringer and transom problems. I plan to go look at the boat Saturday, and want to be sure I don't walk into an immediate restoration. Are there any ways to check this boat without having it taken apart? I would like to be able to use the boat for at least a year or two before having to do any restorations. Any tips/advice/ideas would be greatly appreciated!!
