What would you do?

I set a mild 318 in a '67 Barracuda with 3.55 gears and put the car up for sale. Young man came by and we went for a drive. He said, "I want it!"

Told him to go home and bring his dad back.

Gave his father the keys and said, "Give 'er a test drive."

The dad came back and handed me the keys. "My son will not be buying that car, I want him to live a while longer."
