"The Cobra to End All Cobras" was custom-built for Carroll.
There were several significant sales at this year's Barrett-Jackson auction in Scottsdale, Arizona, such as the first GMC Hummer EV and Ford Bronco to roll off the assembly lines. However, none topped the final price someone paid to own Carroll Shelby's personal 1966 Cobra 427 Super Snake. When the gavel finally struck, the "Cobra to End All Cobras" had a final sale price of $5.5 million. Interestingly, this is about the same amount its previous owner paid back in 2007. The brilliant blue roadster, chassis No. CSX 3015, has quite an interesting history.
Starting out life as a 427 Cobra Competition used for a European tour in 1966, it underwent some major upgrades the following year. The goal was to turn it into the ultimate Cobra 427. The mufflers, windshield, and bumpers were all removed. Very appropriately, it was renamed Cobra Semi-Competition and was (barely) street-legal.
Its bodywork is a combination of Competition and Semi-Competition Cobra features, such as the full windshield found on SC Cobras and the enlarged nose and flared fenders of a Competition model. The three-point chrome roll bar and additional dash instrumentation are two other race-ready touches.
Shelby ordered this car not only for himself to enjoy but also to demonstrate what his relatively small Southern California operation was capable of building. A pair of Paxton superchargers and dual Holley four-barrel carburetors are found on top of a cross-ram intake manifold. Getting that to fit required a custom-built hood with a large enough scoop capable of clearing the air from the blowers.
The estimated 800-horsepower V8 is connected to an automatic transmission because Shelby and crew didn't think a manual could handle that amount of power. Other notable features are a date-coded engine block, headers with spray-painted black chrome-sided pipes, and Shelby's signature on the glovebox and engine. It's never been officially restored because it's already so period correct. And yes, Mr. Shelby himself personally drove it to over 190 mph at the Turismos Visitadores, a Nevada open-road event.
Chances are, CSX 3015 will change hands again at some point, but right now the market has determined its value remains steady. With the onset of vehicle electrification and the eventual end of the combustion engine, Shelby's finest Cobra 427 creation will hopefully one day enjoy an even higher value.
