1965 Shelby Cobra 427 Roadster

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.

The MK III missed homologation for the 1965 racing season and was not raced by the Shelby team. Rumor was that the 31 examples was not enough to homologate the car for production endurance racing. However, it was raced successfully by many privateers and went on to win races all the way into the 1970s.

Shelby’s only choice was to throw windscreens on the unsold cars and sell one of the most radical road-going machines. With that, the remaining cars were detuned and fitted with windscreens to make the perfect street use car. 

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 in the early to mid 1990s. These days an example can currently sell for $1.5 million USD, making it one of the most valuable Cobra variants.

A beautiful and very rare original ’65 Shelby Cobra with a 8.0L Nascar V8 de-tuned from 800bhp to 650bhp. This is a true classic and probably the best sounding car I’ve ever filmed.

Exceptional doesn’t nearly describe this 30,000-mile car. Straight, clean, and reasonably priced at $18,000. Many extras. If you want a 427, you won’t find a better one for sale. Consider a later model Miura or Daytona. No flakes!” This casual advertisement for such a spectacular sports car was answered by Mr. Lonnie W. Stovall of Lake Tahoe, who met Mr. Skiles and purchased the car on the spot. Auction Source: 2007 Monterey Preview
