On June 1, Cain delivered his 2010 automobile to Barr, the operator of a repair shop, for necessary repairs. Barr put the car in his lot on Main Street. The lot, which is fenced on all sides except along Main Street, holds one hundred cars and is unguarded at night, although the police make periodic checks. The lot is well lighted. The cars do not have the keys in them when left out overnight. At some time during the night of June 4, the hood, starter, alternator, and gearshift were stolen from Cain's car. The car remained on the lot, and during the evening of June 5, the transmission was stolen from the car. Did Barr exercise due care in taking care of the automobile?
