Question: Kathleen F. Liarikos purchased a 1984 Jaguar XJS from Pine Grove Auto Sales in 1988. She asserted that Pine Grove made various representations about the car's low mileage. In 1990, after the car had had a variety of mechanical problems, Liarikos discovered that the Jaguar's odometer had been turned back. She then sent a letter to Pine Grove that she asserted was a revocation of her acceptance of the Jaguar. Liarikos received no response from Pine Grove. Liarikos continued to use the vehicle as she needed a car in order to conduct her business. Did Liarikos negate her revocation of acceptance by continuing to use the Jaguar?
