Smith purchased a car on credit from Bobby Floats Toyota, Inc., a month before his eighteen birthday. Smith made regular monthly payments for 11 months but then returned the car to the dealer and made no further payments on it. The dealer sold the car and sued Smith to recover the difference between the amount obtained by the sale of the car and the money Smith still owed to the dealer.. 

Smith refused to pay on the ground the he had been a minor at the time of purchase and had disaffirmed the contract after he reached the age of majority. Will the car dealer succeed in it claim that the ten monthly payments made after Smith turned 18 constituted a ratification of the purchase contract? Discuss.
