1967 Shelby GT500 Super Snake - $ 2.2m

At over twice the price of a baseline GT500, the Super Snake was priced at an unheard of $ 8,000, well beyond its competition, including Shelby’s own 427 Cobra.

The prototype was sold in August 1967 for $5,000. The car made $1.3m in 2013. That number was $2.2m at Kissimmee in 2019.

Maserati 450S

The Maserati 450S is a racing car built to contest the 1957 World Sportscar Championship. A total of ten were made. Between 1956 and 1962, the 450S had 119 appearances, 31 of these being victories. The 450S was the biggest threat to Jaguar, Ferrari and Aston Martin. At the forefront of its competitor’s minds was the awesome 400 bhp V8.

Maserati used the chassis as a test mule for its new 5.7-liter V8 of 5,657cc. The cylinders are inclined at 90 degrees to each other. The naturally aspirated engine was a masterpiece. After 1957 Maserati decided to retire from racing, leaving the 450S as their last great sports racing car. Some went on to racing careers in the US.

A 1956 Maserati 450S Prototype, famously driven and crashed by Stirling Moss, was set to be auctioned in Monaco in 2010. Estimated between £3.3 million and £4.5 million it failed to change hands.
