The Franklin State Bank repossessed the Parker's automobile because of the Parkers' delinquency in payments. At the time, Parker and his son were giving the engine of the car a tune-up in their garage. The vehicle was not mechanically operational because the spark plugs, points, condenser and air filter had been removed. Franklin did not try to determine why the car was not mechanically operational. Instead, after three-days notice to the Parkers, the bank sold the car at a private sale to an auto parts dealer for $50. The bank then sued the Parkers to recover the substantial balance of the purchase price remaining and unpaid. Which party should win the suit? Why?
