1:24 Shelby Cobra 427 S/C Racing Version

AC produced only 23 AC Cobra 427 competition roadsters. In 1966, one was selected and converted into a special model called the Supersnake the "Cobra to End All Cobras." The first one of these was originally part of a European promotional tour before its conversion. This conversion called for making the original racing model street legal with mufflers, a windshield and bumpers amongst other modifications. But some things were not modified, including the racing rear end, brakes and headers. The most notable modification is the addition of Twin Paxton Superchargers, TPS. Shelby crafted two 427 models, adding the TPS to each, they were built from cars with the serial numbers CSX 3303 and CSX 3015. He gave one of the two cars, CSX 3303, to comedian Bill Cosby, a close friend, and kept CSX 3015 for himself. Shelby' car was converted from one of the 427 SC (Semi-Competition)Cobras. Cosby' car was a later street car converted to a Supersnake.

When Cosby attempted to drive his CSX3303, he found that it was very difficult to keep under control; he later recounted the experience on his 1968 stand-up comedy album 200 M.P.H.. Cosby gave the car back to Shelby, who then shipped it out to one of his company's dealers in San Francisco, S&C Ford on Van Ness Avenue. S&C Ford then sold it to customer Tony Maxey. Maxey, suffering the same issues as Cosby did with the car, had his throttle stick while leaving a traffic stop, lost control and drove it off a cliff, landing in the Pacific Ocean waters.[18]

Shelby used his CSX 3015 as a personal car over the years, sometimes entering it into local races like the Turismos Visitadores Cannonball-Run race in Nevada, where he was "waking [up] whole towns, blowing out windows, throwing belts and catching fire a couple of times, but finishing."[19] CSX3015 was auctioned on 22 January 2007, at the Barrett-Jackson Collector Car Event in Scottsdale, Arizona, for $5 million plus commission (£2.8 million), a record for a vehicle made in the U.S.[20][21]
