Bentleys have worn the Continental Flying Spur name on two quite different classes of four-door cars since 1957.The first is a four-door saloon body made to special order by coachbuilders H. J. Mulliner & Co. (later Mulliner Park Ward) on a Bentley Continental chassis. These bodies were built in London on the various specification chassis made in Crewe between 1957 and 1966. The second is a standard manufacturer's catalogue car, a four-door standard production line version of Bentley's own Crewe factory-built Continentals. Both may be described as four-door variants of 2-door Bentley Continentals.
