Sperry Ford sold a car to Bowling when Bowling was only 16 years old. Once Bowling had paid the full purchase price in cash, Sperry turned over the car and the certificate of title. After driving the car for only a week, Bowling discovered that the main bearing was burned out. When Bowling found out that repair costs would almost equal the price he'd paid for the car, he left the car on Sperry's lot and asked for his money back. Sperry Ford refused to give Bowling his money. Was Sperry justified in this refusal? Explain. [See: Bowling vs. Sperry, 184 N.E.2d 901
