Headlining the Bonham’s sale on April 23, coinciding with the Monaco Historic Grand Prix weekend, is a very special 1936 Delahaye 135 S.

“Blue Buzz II,” as the car was nicknamed thanks to its engine sound, ran at Le Mans and at the Three Hours of Marseille.events, as well as Donington, Pau and Commiges as part of the Ecurie Bleu racing team owned by American heiress Lucy Schell.

The car had several styles of bodywork, and it’s in the more streamlined 1939 Chappes Frères embodiment that she will be offered at auction in Monaco.

Unsurprisingly, the car won a number of concours d’elegance prizes over the years. With its original period engine and chassis, the car is something of a rarity from the pre-war era, Bonhams have said.

The expected price is between 800,000 and 1.1 million euros.
