Kathy was shopping for a new car and had a 2008 Toyota Corolla to trade in. In the negotiating process, the appraiser at the dealer took her car for a test drive to aid in the appraisal process. Kathy had found a car she liked and began negotiations in earnest. They settled on a price for the new car, with a final agreement contingent on an acceptable amount for the trade-in. When the sales manager brought a contract showing the price of the new car, with the deduction for the trade in, it noted "2009 Corolla" as the car traded in. Everything else in the car's description (mileage, etc.) was correct. Kathy noticed this but said nothing and quickly signed the contract. A few minutes later when Kathy went to sign over the certificate of title on her old car, the sales manager said that the deal was off because he had based his trade-in allowance on the car being a 2009 model. Kathy said she would take the deal only as it was, and would not accept a lower trade-in allowance. After some further negotiations, the dealer agreed to grant the trade-in allowance as originally stated. Kathy signed over the title and took the new car home. The next morning, the sales manager called and said that the dealer was rescinding the contract based on the mistake. Discuss the issues and how this case would turn out.
