Please help me with IRAC of this case Sedmak v. Charlie's Chevrolet, Inc.

FACTS from online: Dr. and Mrs. Sedmak (Plaintiffs) discovered that Chevrolet intended to manufacture a small number of a limited edition Corvette, the Pace car. Dr. Sedmak contacted Charlie's Chevrolet, Inc. (Defendant) to inquire about the car and Kells, Defendant's sales manager, told him that a deposit would be required. Mrs. Sedmak hand-delivered the deposit to Defendant and received a receipt. While there, Mrs. Sedmak ordered upgrades to the standard equipment. According to Kells, he did order the upgrades, but ordered them because they would be better for the car, rather than because Plaintiffs wanted them. Mrs. Sedmak said that Kells told her that the car would cost about $15,000, but Kells denied discussing price. Kells notified Plaintiffs when the car arrived at Defendant, but informed them that they could not buy it for the price quoted because there had been so much demand for it that the price had inflated. He also notified them that they could bid on the car, but they did not submit a bid. Plaintiffs sued for specific performance in the trial court. The trial court granted specific performance. Defendant appealed to the Missouri Court of Appeals.
