It's all in the service records, as if transmission fluids were filtered per manufactures recommendations along with all other services like belt, hoses, wires, distributor, brakes, tires. Figure 7 tires if needed are about $2500. other services could be another $3,000 to get it roadworthy. The brakes probably will have rusted to the races so have the races greased first thing as they are known to not retreat and hold on to rotors causing drag and hot spots. Then the roof may need replacement if it's original at about $4500. If it needs just routine work and everything else is done it's probably worth around $20,000.
