BMW’s all-new Z4 roadster makes the Porsche Boxster look mundane in comparison and offers concept car looks that will shock even Aston Martin Zagato owners. Simply stunning and a definite winner in design and execution. BMW has once again shocked the sports car segment with an outstanding looking roadster that also looks great inside. We are sure this will be the centerpiece for the BMW display at the coming Frankfurt Motor Show. More information on the engine and specifications will be shared later today.
