I think $4700 is a higher end price--at that price I would want the car to be rust free--underneath as well as on top--do you know about the magnet test, a weak magnet won't stick to bondo, and will not stick as well if there is a thick layer of bondo with metal underneath. Test the rockers and the area at the bottom of the small strip between the front fenders and the front door, they like to rust there.
Also at that price should be mechanically good, check synchros, doesn't pop out of gear, doesn't whine a lot in first or reverse (a little is normal) good oil pressur (20-30 at idle, 50-60 at 3000 RPM or so.
That is just a start, make sure front suspsension is tight too.
Gotta run good luck
