The Daimler Regency DF300 series was a luxury car made in Coventry by The Daimler Company Limited between 1951 and 1956. Only 52 examples of the first Regency were made because demand for new cars collapsed just weeks after its introduction. Almost two years later a lengthened more powerful Regency Mark II DF304 was announced but, in turn, it attracted few customers and it was replaced by the very much faster up-rated One-O-Four DF310 announced in October 1955.
