It's believed to be—and documented as—the only matching-numbers four-speed 'Cuda convertible in existence. In addition to its blue paintwork and matching wheels, the 'Cuda features deck-lid brightwork and wide sill strips, with dog-dish hubcaps, white-lettered tires and the famous (and rare) Shaker hood. There's a set of chromed dual exhaust tips, color-matched Bright Blue interior trim, an 8,000 rpm tachometer and 150 mph speedometer.
What's under the hood is important too, of course—the standard 426/425 HP Hemi, and a four-speed manual transmission—making the model one of just two four-speed cars delivered in the U.S. The other, while still in existence, no longer runs its original engine and transmission, making the Mecum example truly unique and going some way to justify its staggering auction price. The price is fitting too, in that it was a Hemi 'Cuda convertible that became the first muscle car to cross the million-dollar mark at auction, back in 2002.
