I have to tell you that it's not worth it to 'restore' it. Of course it's worth it if you're attatched to it to do everything you can to keep it in tip-top shape, though. Little things like fixing blemishes and making sure any signs of rust are taken care of is a good idea. Fix anything that doesn't seem to work quite right any more. Replace door hinge pins, hood and hatch struts, etc... Maybe weatherstripping and/or seals that are showing their age. One day, it may be worth a bunch of money again and a resto would be much easier if you take the basic steps now.
