The 1939 and 1940 Indianapolis 500 races were won by Maserati with 8CTF 'Boyle Special'. Wilbur Shaw almost scored a victory for the third time in 1941, but was forced to withdraw with a broken wheel. Maserati would return to Indy 500 with a 420M/58 for its 1959 edition. The car, previously damaged, was repaired and slightly rebodied to fit a different race requirements. The "Carrozzeria Allegretti e Gentilini" removed the rear fin and lowered the hood scoop. The engine oil tank was repositioned to the left for better weight balance. The livery was finished in Italian racing red but still retained the Eldorado sponsorship name and logos. The intended driver was Ralph Liguori representing a privateer Eldorado Racing team.
