The MINI Cooper and Cooper S Convertible offers the same driving pleasures as the hardtop versions, including the optional John Cooper Works kit with an engine performance upgrade kit, limited-slip differential and upgraded brakes. Making it unique among convertibles is a fully automatic convertible roof with an integrated power sunroof so you can enjoy open-air motoring without putting the top all the way down. In standard mode, the MINI Convertible’s roof opens or closes in about 15 seconds.
