There were only 31 "original" Shelby Cobra 427 S/C cars produced. The originals are the cars carrying the CSX-3xxx serial numbers. There were an additional 19 full competition cars produced and 260 street cars. The street versions had either a 427 or 428 engine, no roll bar, no side pipes, and were intended to be the production Cobra. What most people don't realize is that Shelby American still produces Cobras today as what are known as "continuation" series cars. They are also CSX serial numbered cars, but in the 6000 series. They also produced a run of CSX-1xxx cars a few decades ago. Other CSX cars are produced by Superformance, which is a licensed manufacturer in South Africa that produces CSX-4xxx, CSX-7xxx, and CSX-8xxx serial numbered cars. Our beloved model is likely based on the current CSX-6xxx series from Shelby American. The CSX-6xxx cars are made-to-order and some are made with the roll bar harness mounts. Again, no two Cobras are exactly alike, and the vast majority are replicas of the original 31 cars produced.
