The red 335 Sport Scaglietti won the 1958 Cuban Grand Prix and established a lap record at the Le Mans 24 Hours race.
It was driven by top motorists of the period, including Britain’s Stirling Moss and Mike Hawthorn.
Matthieu Lamoure, handling supervisor of Artcurial Motorcars auction house, stated it was a world record rate for a car in euros.
The last record was held by a Ferrari 250 GTO which chose 28.5 m euros in 2014.
Motoring reporters say at current exchange prices, it becomes the globe’s 2nd most costly vehicle in bucks, as the 2014 sale in California was for $38m.
The brand-new owner was explained only as an “international customer”.
The 335 Sport Scaglietti was just one of only four versions to come out of the Ferrari factory.
