 For buses and dual-purpose vehicles, a BET standard design of bodywork was produced, primarily by Marshall and Willowbrook but also to a lesser extent by Weymann and Metro-Cammell.Another major English customer for the Leyland Leopard was Barton Transport of Chilwell near Nottingham, which built up a fleet of 200 with Plaxton Elite and Supreme coach bodywork.Unusually for a large operator, Barton standardised on this type of vehicle for all types of work including local stage carriage services; for this reason, all were fitted with a wide two-piece door, known as an "express" or a "grant" door.
