The Ferrari 550 Maranello is one of the most important modern cars by the Italian manufacturer, as it marked its return to a front-engine, RWD layout for its two-seater 12-cylinder model. The first such model in 23 years, the 550 Maranello was introduced in 1996 and updated in 2002.

The facelifted model was renamed the 575M Maranello and spawned a limited-edition Superamerica model. While the 575M Maranello was produced in a little over 2,000 examples, the Superamerica was capped at just 599 units. And one of these rare examples is now for sale in the U.K. by Bell Sport & Classic.

But the latter was far from usual. Instead of a regular panel that you can remove and place in the trunk, Ferrari conceived an electrochromic glass panel that rotated 180-degrees at the rear to lie flat over the trunk.

The roof, which incorporates a carbon-fiber structure that is hinged on the single axis with a luggage compartment lid, was developed in cooperation with French glass specialist Saint Gobain. This roof design was reportedly inspired by the one built by Alfa Romeo for the Vola concept, unveiled five years before the Superamerica.

The power and torque output were actually identical to the Ferrari 612 Scaglietti. Alongside the latter, the Superamerica featured the second most powerful version of the F133 series engine, behind the 575 GTC, rated at 597 horsepower. Discontinued in 2011, this engine was based on the F116 design that Ferrari introduced back in 1992.

The model available through Bell Sport & Classic is equipped with the HGTC Pack, which adds ceramic brakes, modular alloy wheels, Scuderia shields, and Daytona seat inserts. It also features an optional sports exhaust.

This Superamerica is finished in the popular Rosso Corsa exterior paint, paired with Crema-colored leather upholstery. It has only 19,000 miles on the odometer and just one owner since it was built in 2006. The asking price is £239,950, which converts to around $295,600 as of June 2020.
