1955 Ferrari 410 S with Carroll Shelby winning the championship

Before he founded Shelby American In the early 1960s, Carroll Shelby was racing around the world in cars from other manufacturers, not just American ones.

In 1959, he won the 24 Hours of Le Mans together with Roy Salvadori, driving the Aston Martin DBR1.

He also drove several Ferraris in the 1950s, including two of the four 410 S cars developed to compete in the Carrera Panamericana before it was cancelled in 1955. Two of the Ferraris Shelby drove were sold to private individuals. The other two remained with Ferrari’s own factory team.

One of the two privately owned cars, chassis number 0598 CM, was sold at auction in 2022 for $22 million. It was also driven by Juan Manuel Fangio and Phil Hill, among others.

Now, another 410 S driven by Shelby (chassis #0592 CM) is set to go under the hammer at RM Sotheby’s during the 2024 Monterey Car Week next month. It has a different provenance than chassis #0598 CM, so it’s estimated at just “over $15 million,” but it’s still been driven to victory by multiple drivers, including Shelby.

The highlight was Shelby’s win at the 1956 Palm Springs Road Race. According to the listing, Shelby had a falling out with the car’s owner, Tony Parravano of Scuderia Parravano, soon after the race and soon joined a rival team led by John Edgar. Under Edgar, Shelby drove chassis number 0598 CM to a string of wins.

The CM in the chassis code stands for “Carrera Messicana,” as these cars were developed for the Carrera Panamericana event in Mexico. With a body designed by Scaglietti, chassis number 0592 CM is arguably the most original of the four prototypes. Aside from being fitted with a matching-numbers 5.0-liter V-12 engine, this car was never damaged in its brief racing career.

According to the listing, Paravano fled to Mexico for tax reasons in 1957, taking chassis number 0592 CM with him. After his death, the car was sold to Javier Velasquez, one of the organizers of the Mexican Grand Prix. The car was later acquired in 1970 by Pennsylvania architect Robert Dusek, who kept it for the next 37 years.

The current owner purchased it at an auction in 2014 and has since fully restored it.

The RM Sotheby’s auction will be held from August 15 to 17. Other highlights include a 2006 McLaren Formula 1 car and a 1995 Ferrari F50.
