The Regina, DF400 and DK400 chassis was generally equipped with steel limousine bodywork by Carbodies (identified as DK400B) with a drop division, three occasional seats and more luxurious trim in the rear compartment than in the DK400A owner-driver car.

The Regina limousine was shown at the Earls Court Show in October 1954 and then described as being built on a special edition of the Regency chassis.
Some chassis were bodied as hearses and at least one was equipped with a coupé body for Lady Docker.

An unusual feature of the limousine was that the occasional middle seats were three abreast.
