Take it for a drive and make sure it's solid. Check the lower intake manifold gasket. If it has never been replaced, it needs it. Look at the front bushings on the lower control arms. They tear and/or separate from the control arm. Check the wheel bearings for play. Being a New England car, I would look at the rockers along the pinch weld and see how bad the rust is. I've seen some GP's that had scary amounts of rust there. Good luck with the search and welcome to the forums.
