The third-generation MINI Convertible (code name F57) marks a major turning point in the model's history. Based on BMW's modular UKL1 platform, it definitively abandons the notorious 'Prince' engines (developed with PSA) in favor of BMW's modular B-series engines (B38 3-cylinder, B48 4-cylinder). This technical change propels the F57 to unprecedented reliability standards for the brand. The model benefited from two facelifts (LCI in 2018 with the arrival of 'Union Jack' taillights and DKG dual-clutch gearboxes, then LCI 2 in 2021 with a streamlined front end). Although rear space and trunk remain symbolic, the quality of finish, driving pleasure ('Go-Kart feeling'), and soft top kinematics (including a sunroof function) make it a benchmark in the premium small convertible segment.
The MINI Convertible F57 is undoubtedly the most accomplished and recommendable generation on the used market. The adoption of BMW engines has eradicated the reliability nightmares of the previous generation. The Cooper (1.5L 136 hp) version represents the most balanced choice for daily use and cruising, while the Cooper S (2.0L) will delight dynamic driving enthusiasts. Purchase is highly recommended, provided the soft top's condition is checked and engine mounts are replaced around 80,000 km. Avoid the rare diesel versions, which are unsuited to the philosophy of a pleasure convertible.
