Need some opinions

That is one sweet find! I agree with the others, get it running well and check/replace all the items that can age and cause problems (belts, hoses, brakes, fuel system, tires, etc) and drive it for a while. You might find you like it as is. J par is right, don't get upside down on the car. It's easy to have $10K in a $2K car. Ask me how I know.
