Mini vehicles are equal parts quirky and fun to drive, whether you have the classic two door or the more practical four-door version. Base Coopers use a turbocharged three-cylinder that sounds a bit gravelly and returned 31 mpg overall with the six-speed automatic. The more-powerful and nicer-sounding Cooper S uses a four-cylinder turbo and got 30 mpg with the six-speed manual. Handling is nimble and sporty but not as agile as previous generations. The ride is rather firm and road noise is noticeable. Controls take some getting used to, and the backseat is still tiny. Options easily push the price past $30,000. A hot-rod John Cooper Works bumps the power to 228 hp and gets firmer suspension. Reliability has dropped to below average.
