I am sure you know how to gauge the problems with the car i.e. smashed body, or mechanical / electrical issues. And just by taking off the valve covers you can get a good idea of the condition. If there are any fluids left check them too. The lower rad hose usually has some fluid left in it.
Any way it sounds like you are looking for a pep talk. I say do some up keep gasket replacement and timing chain, water pump and rock it. What's the worse that could happen????
