If you've got a Ferrari Roma in your garage, life's pretty good. But as far as the Prancing Horse is concerned, you're a nobody. Anyone can buy a supercar, but if you're one of Maranello's special clients, they'll build you a bespoke motorcar through the Special Projects program. The wheeled sculpture you see before you is just that. It's called the SP51, and it's the latest vehicle to join the ever-growing One-Off Series from Ferrari.

This elegant roadster is based upon the already incredible 812 GTS but sets itself apart with unique styling. Those bewitching good looks come courtesy of Flavio Manzoni's Ferrari Styling Center, where designers set the elegant roadster apart with stunning details. Perhaps the most interesting aspect is the lack of a roof; Ferrari says this makes it an "authentic roadster." Even when parked, the SP51 looks like the ultimate al fresco motoring experience.

The rich, three-layer Rosso Passionale paintwork was developed exclusively for the SP51 and suits the curvaceous bodywork to a tee. A blue and white stripe stretches over the lengthy hood and rear of the vehicle, and even makes an appearance in the interior. The Prancing Horse says this was inspired by a legendary example of the '55 Ferrari 410 S.

Other striking elements include the dramatic flying buttresses, which lend the Ferrari a muscular feel. These both flow gracefully into the rear fascia, where you'll find the spoiler. Sited just beneath are the taillights, which appear as if suspended in mid-air. Overall, there's a hint of Ferrari 550 Barchetta to the rear of the SP51.

Up front, specially designed headlights mark the bespoke creation out as something different. Further up the hood, you'll find bare carbon fiber, which visually conceals the air vents. The lightweight material has been used liberally and can be seen on the side skirts, front bumper, and rear.

Like the elegant paintwork, the five-spoke wheels seen here are also specific to the SP51. Each spoke has a carbon fiber wing profile and also features a diamond-cut finish on the outward-facing parts of the respective spokes. Being Ferrari, this one-off is so much more than a pretty face.

Getting the aerodynamics right was a tall order and required rigorous wind tunnel testing and CFD simulations. This will ensure that the roofless Ferrari is a joy to drive, with minimal wind intrusion and buffeting.

The cabin, however, is where the best work has been done. Working closely with the SP51's owner, Ferrari recreated the Rosso Passionale hue as the main color for the interior Alcantara.

The seats and dashboard have been trimmed in the exclusive shade of red. The exterior stripe, as mentioned, has been extended to the interior and can be seen between the seats.

Keen on furthering the theme, Ferrari has used a blue Kvadrat insert with white cross-stitching for the seats and various interior elements. Lastly, the SP51's cabin boasts glossy carbon fiber trim inlays.

The one-off creation is Maranello's first front-engined V12 spider in half a century. It will soon head to its new owner in Taiwan, someone Ferrari describes as a "special client" and one of the company's leading collectors. Of course, there's no mention of cost but, as you can imagine, it must have been a rather expensive affair. After all, the 812 GTS sold new for more than $400,000.

No mention is made of performance, with Ferrari claiming only that the SP51 inherits the layout, chassis, and engine from the 812 GTS. This likely means outputs remain unchanged from the 6.5-liter V12 engine, which produces a phenomenal 789 horsepower and 530 lb-ft of torque, good enough to propel the 812 GTS up to 210 mph.
