The Ferrari 575M Superamerica is the final development and only convertible of the Maranello series. It features a brilliantly simple rotating glass roof which flips over your head and sits out of the way on top of the boot. The roof also features clever electro-chromatic glass which means that a small current can transform it from virtually opaque to transparent within a few seconds. Drivers get to enjoy an unhindered luggage space and of course, the sound of the sublime V12 engine. This little-known car was Ferrari’s first hardtop convertible.
