The V12 250F was a prototype for Juan Manuel Fangio, a five-time Formula 1 champion. Only one car was produced. Engine problems, however, prevented Fangio from qualifying for the Monaco Grand Prix in 1957. A six-cylinder 250F did race in seven Formula 1 seasons, win the World Driver’s Championship in 1957 and had the honor of introducing the first woman to compete in a Grand Prix in 1958.

The 420M 58 “Eldorado” lightweight racing machine was commissioned by Eldorado Sud, an ice cream company, in 1958 to compete in the 500-mile Race of Two Worlds. Renowned driver Stirling Moss signed on for the job. When the steering broke at 250km/h he was forced to exit the race, later saying it was the scariest motor racing accident of his life, according to Maserati. The unique Eldorado was capable of speeds of more than 200 mph, according to Rabold.
