Police departments regularly sell older model Crown Victoria cars, usually as part of a police auction that includes a variety of other vehicles. Buyers find these auctions by visiting the police department section of local government websites or by visiting sites such as GSA.gov or PoliceAuctions.com
GSA.gov features a vehicle auction page that lists sales of all used cars formerly in use by various government entities, including police cars. PoliceAuctions.com contains listings for all types of merchandise sold by police departments, with a section dedicated to auto sales. Buyers also find local police auctions or sales of Crown Victorias by contacting a local department and asking about vehicle auctions.
