In 1967 Shelby had finished 31 427 competition cars. These were strictly race spec cars that were tuned to have somewhere between 400 and 500 horsepower. Unfortunately, the 31 examples was not enough to homologate the car for production endurance racing. Shelby's only choice was to throw windscreens on the unsold cars and sell one of the most radical road-going machines. In 1967 the 427 S/C was the fastest accelerating production vehicles.
Due to the very limited numbers involved with the road going version of the 427, these cars have fetched anywhere from $200 000 to $500 000 USD
