The prototype, which lacked an engine, had all the luxury features of the standard saloon but a shorter wheelbase. Painted "Seafrost" it was named after a 1931 Daimler Double-Six with a body by Corsica. Jaguar Daimler Heritage Trust have commissioned it to operate as a fully functional road-legal car[164] and it is on display at The Collection Centre at the British Motor Museum at Gaydon, Warwickshire, England.
