1965 Ford Mustang

I am selling this 1965 Ford Mustang for my father. He has owned the car for around 2 years. The car runs great but is not driven much at all, maybe 5-10 miles have been driven since purchase. Once a month or so he will start the car and let it warm up and idle a bit. The car is always covered and Garage kept. He paid 16k, I’m not sure if that was fair or not, but if not, he will just keep the car if we can’t come close to what he paid. .
