Having heard nothing from OReilly by May 15, Newtown Motors sold the car to another party. On May 25, OReilly told Newtown Motors that he accepted the offer and tendered $12,500. When Newtown Motors told OReilly it had sold the car to another party, OReilly claimed Newtown Motors had breached their contract.
