Our Verdict
The MINI Cooper is all about character — nothing else in the class delivers the same go-kart driving feel and retro-modern design. The F56 (2014–2023) uses BMW-derived engines that are significantly more reliable than the problematic Prince engines of the previous generation. Running costs are higher than a Fiesta or Polo, but the ownership experience is unique.
Introduction
The MINI Cooper has been an icon of British motoring since BMW relaunched the brand in 2001. The F56 generation (2014–2023) was the most refined and reliable MINI yet, built on the BMW UKL platform and using a range of BMW-derived turbo engines.
Available as a 3-door, 5-door, Clubman (estate), and Countryman (SUV), the MINI range covers a surprisingly broad market. The Cooper S (192hp) and JCW (231–306hp) are genuine performance cars with a devoted following.
As a used buy, the F56 MINI represents a big improvement over the R56 generation, which had known reliability issues. The BMW engines are more robust, and the platform is more polished. However, MINI ownership still comes at a premium — servicing, insurance, and parts are priced closer to BMW than Ford.
