The MINI Cooper S ADO20 was built from 1967 to 1970.
The Cooper Cooper S Mk II, the most traded version: The Mk II Cooper S represents the sweet spot of classic Mini evolution, refining Alec Issigonis's revolutionary design without losing its raw character. Built from 1967-1970, this generation introduced the distinctive grille-mounted headlights and improved interior space while maintaining the pure driving dynamics that made Minis giant-killers on track and road. The 1275cc A-series engine delivered 78 hp through a close-ratio four-speed, enough to embarrass much larger cars in the hands of a skilled driver. With only 6,300 produced at Longbridge, the Mk II S is significantly rarer than its Mk I predecessor, making genuine examples increasingly coveted. The improved build quality and refined ergonomics make this the most usable classic Cooper S for modern driving, while period racing provenance and Monte Carlo Rally heritage ensure strong collector demand. Values have climbed steadily as enthusiasts recognize the Mk II as the most developed iteration of the original Mini formula.
