The 1972 Reliant Regal represents the final chapter of one of Britain’s most iconic three-wheelers, produced just a year before it was succeeded by the equally famous Reliant Robin. By 1972, the Regal had matured into the 3/30 designation, powered by a lightweight, all-alloy 701cc overhead-valve engine that produced a modest 30 hp—a setup that allowed it to be driven on a motorcycle license due to its sub-455 kg curb weight. This specific year is most culturally resonant for the Supervan III variant, which gained worldwide immortality as the battered, yellow "Trotters Independent Trading" van in the sitcom Only Fools and Horses. Despite its reputation in comedy for being prone to tipping, the 1972 Regal was a feat of pragmatic engineering, utilizing a rust-proof fiberglass body bonded to a steel chassis to provide affordable, weather-protected transport for the masses. Today, it is a quintessential piece of British nostalgia, celebrated as much for its quirky engineering as for its status as a beloved underdog of the automotive world.
