My opinion. Are your aware of all that goes wrong on a car that's not used for 10 years? Brake system will be needing a full flush and rebuild. The carb gaskets will be dried and shrunken. Rebuild. Shocks shot, springs sagging, all rubber parts will crack when you start using the car. So, all tie rods, ball joints, etc. will fail quickly if not already shot. Gas tank ….. if not full of rust, full of gunk. Some cars of that vintage have nylon timing chain gears. The teeth will sheer. The fuel pump diaphragm will be dry rotted. I may last a week or so but … The least of your worries is if it runs. The engine if carefully prepped before starting will be as it was when parked. The ring gear will be rusted in the diff where it's not in the oil. Usually not a problem but …. Even if in spectacular shape be ready to replace lots of parts.
