Closed van and open flat-bed ("pick-up") versions of the Minor were built from 1953 until the end of production. They were designed for commercial use with small businesses, although many were also used by larger corporations. Van versions were popular with the General Post Office, the early versions of these (to around 1956) having rubber front wings to cope with the sometimes unforgiving busy situations in which they were expected to work. Both the van and the pickup differed from the monocoque construction of the Saloon and Traveller variants by having a separate chassis. They also differed in details such as telescopic rear dampers, stiffer rear leaf springs and lower-ratio differentials to cope with heavier loads.
