This fabulous 1956 Maserati 450S Prototype will cross the block this May in Monaco, where it will be offered by RM auctions and is expected to fetch a staggering sum. The car was originally driven by Stirling Moss during the 1956 Mille Miglia as a 350S. After its brakes failed and it hit a tree, Maserati restored the car to improved status - making it a test vehicle for the 450S race car. This wasn't a huge success either, and the car crashed again, this time due to transmission issues.
The ill-fated car was given a new lease of life in the 1980s, when it received a new V-8 engine and triumphantly returned to the same race. As one of just 11 examples of the 450S ever to be built, it is expected to fetch between $5.5 million and $7.5 million at next month's auction.
