Most disappointing of all, this kind of aggravating Mini experience isn’t a new one for us. It’s an echo of the quality we witnessed during long-term tests of a 2009 John Cooper Works Convertible and a 2011 Cooper S Countryman. This story should be a discussion of the Mini’s rough ride, its animated engine, the inflated price, and its spry handling. But we can’t write that story because, for 21 months, we were antagonized by maddening noises and the accompanying headaches. Despite that, there’s still some lemonade to be made: Our 2014 Mini Cooper S never left anyone stranded.
