Unbelievably, this Metro was not offered as a "factory backed" conversion, even though it came with a blue chip pedigree. John Cooper Garages offered this car (later renamed the Metro Monaco for legal reasons) as a conversion on customers' own cars...
Metro-Cooper
That most illustrious of names associated with the Mini during the 1960s made a welcome return in 1981 when John Cooper introduced his own Metro Cooper, as sold through his own ARG dealerships. Unlike the Janspeed and Turbo Technics performance Metros, the Cooper Metro relied on the adoption of a twin carburettor set-up, a wilder cam profile and freer flowing exhaust system. It was a formaula that had proven to work wonders on the Mini, and it had the same results on the Metro. The Metro Cooper may have not been as quick as the turbocharged alternatives (0-60mph was timed at 11.0secs by Motor magazine), but it certainly acted as an accurate preview to the 1982 MG Metro 1300, right down to its Wolfrace Sonic wheels.
