Mercedes-Benz SLS AMG Roadster: The best thing about this car is the fact that it is a convertible and therefore has normal doors unlike the gullwings found on its hard-topped counterpart. With the roof down it's easier to hear the howl from the engine and the startled look on people's faces as the car screams past. However, despite the monstrous straight-line performance, the SLS doesn't like sharp corners, despite costing $280,000. Photo:AFP
