In addition to the formal Crown Imperial, Imperial also fielded the slightly less formal, more sporting Imperial Crown series for 1957. This lively model line included the beautiful Crown Southampton 2-door hardtop.

Imperial suggested that drivers "Test its tremendous, satiny power. Feel its brilliant ease of handling. Revel in its instant, perfect obedience. Know all the minute-to-minute pleasure reserved for the man who drives the triumphant Imperial."
