Glenn Grove bought a 1936 Pontiac from Bernard Stanfield. Stanfield signed the certificate of title, which stated that the car was sold for $1,000. No other terms of sale were mentioned in the certificate, and none were incorporated by reference. Three years later, Stanfield filed a suit against Grove in a Missouri state court, claiming that Grove still owed $9,000 on the price of the car. At the trial, Stanfield testified that he and Grove had an oral agreement by which Grove was to pay $1,000 for the "title doent" and $9,000 for the actual car. The court entered a judgment in Stanfield's favor. What will happen on appeal? Explain.
