The Ford Crown Victoria (commonly nicknamed the Crown Vic) is a rear-wheel drive full-size car first produced by the Ford Motor Company for the North American market in the mid-1950s. Its current incarnation has been in production since 1992 at Ford’s St. Thomas Assembly plant. While the Crown Victoria shares its platform and components with the Lincoln Town Car, it shares almost no exterior sheet metal or interior parts. One version called Ford Crown Victoria Skyliner had the front part of the roof, in front of the steel band, in acrylic glass. This made the car difficult to sell, especially in the southern states in USA. Thus few Skyliners were made. Most of them ended up in Sweden, possibly because the climate was more suitable for an acrylic glass roof.
