The main thing to look for (on any old car) is rust. There is 0 body parts available for the most part, you will have to make them if they are gone. On the other hand I have bought several cars that have sat for a decade or more. The gas tank always is full of crud, all brake lines are collapsed, and fuel lines shot. If you can buy it right, you should do it. If you get into it & change your mind, you can always sell it, just don't dismantle it unless your 100% sure you will put it back together.
