If you're planning to buy a V12-powered Ferrari, be prepared to wait a long time for an 812 Superfast because the flagship supercar is sold out for the next five years. An opportunity has arisen, however, to own the next best thing: we're talking, of course, about its predecessor: the Ferrari F12 tdf. One of only 799 ever made, a unique example of the F12 tdf will be going under the hammer at Mecum's upcoming sale in Indianapolis next month, which takes place between May 15-19.

It's only covered 1,157 miles since it rolled out of the factory last year, features over $92,000 worth of options including a $10,124 Ferrari Telemetry system, and has even been signed by Sebastian Vettel. It's also finished in 'Ferrari Rosso F1 2007,' which could be a bespoke paint scheme and explain why it bears the signature of a Formula One driver. If you need a recap, the more hardcore tdf packs a naturally aspirated 6.3-liter V12 producing 769 horsepower and 520 lb-ft torque. That's enough to send it rocketing to 62 mph in 2.9 seconds before hitting a top speed of over 211 mph. For comparison, the 812 Superfast's 6.5-liter V12 produces 789 horsepower and 530 lb-ft of torque.

That makes it the most powerful naturally aspirated engine ever fitted to a production car, but then the F12 tdf isn't exactly slow either. What makes the F12 tdf stand out, however, is that only weighs 3,120 pounds, making it significantly lighter than the 3,362-pound 812 Superfast. As a result, both cars have the same top speed and 0-62 mph time, but we suspect Ferrari will eventually roll out an even more hardcore version of the Superfast that will be the equivalent of the F12 tdf. There's no reserve price for this particular example, but given its limited availability you can bet it will sell for an astronomical figure.
