The Daimler Regency series was a luxury car made in Coventry by The Daimler Company Limited between 1951 and 1958. Only an estimated 49 examples of the 3-litre Regency chassis were made because demand for new cars collapsed just weeks after its introduction. Almost three years later in October 1954, a lengthened more powerful Regency Mark II (DF304) was announced but, in turn, after a production run of 345[3] cars, it was replaced by the very much faster, up-rated One-O-Four (DF310), announced in October 1955.
