So here I have the Cooper S Convertible with the 189 horsepower turbo decked out in the highest Iconic trim level replete with silver bonnet stripes and the MINI Yours soft top for an as-tested price of $40,850. Now, there’s always some sticker shock with the MINIs I test and this one isn’t any different but a less-equipped Convertible can be had for under $29,000.
