1965 Ford Mustang

I am selling this 1965 Ford Mustang for my father. He has owned the car for around 2 years. The vehicle runs great and is not regularly driven at all, maybe 5 miles have been driven since purchase. Car is always covered and Garage kept. He paid 16k for this car. I’m not sure if that was fair or not but if not we will just keep the car if we can’t come close to what he paid. .
