Bonhams Les Grandes Marques à Monaco 2021 Sale

The Bonhams ‘Les Grandes Marques à Monaco’ sale was held on 23 April 2021 at the Fairmont Monte Carlo hotel during the Monaco Historic Grand Prix weekend (23 – 25 April 2021). It was a live auction.

Bonhams had previous successes at the biannual auctions during the Monaco Historic Grand Prix weekend. The 2020 sales were canceled but in 2018 Bonhams sold the 1993 McLaren MP4 that Ayrton Senna drove to his record sixth Monaco Formula 1 Grand Prix victory sold for $5 million. Senna’s first Monaco racer – a 1984 Toleman-Hart – sold for a sensational $1.9 million in the same sale.

A rare 1936 Delahaye 135 S Compétition Court racing car, known as ‘Buzz II’ which campaigned in 1930s endurance races including the 24 Hours of Le Mans, was the top lot of Bonhams The Monaco Sale ‘Les Grandes Marques à Monaco’ 2021. It sold immediately after the auction for an undisclosed amount within the estimate, which was €800,000 – 1,100,000 ($950,000 — $1,300,000). 

The 135 S made its track debut at the 1936 ‘Three Hours of Marseille’ endurance race 1936 as part of Écurie Bleu, the three-car semi-works team of Lucy Schell former racing driver and the first female motorsport team owner. The cars’ sky-blue paintwork, together with the muffled ‘buzzing’ sound of their engines earned them the nickname Blue Buzz’. 

Blue Buzz II competed in pre-war Grand Prix races at Donington, Pau and Commiges and endurance races such as the Belfast Tourist-Trophy before its greatest challenge, the 24 Hours of Le Mans in 1939. 

The 135 S was offered with coachwork in the style of the Chappes Frères bodyshell, retaining its original period running gear, engine and, most importantly, the original chassis –a rarity for a racing car of this period. 

1991 Isdera Imperator 108i

The top result achieved during the Monaco 2021 auction was for a rare gull-winged supercar –  a 1991 Isdera Imperator 108i, that sold for €690,000 ($832,500). It was one of only 30 examples ever produced.

The wedge-shaped Imperator was the realization of the Mercedes-Benz design experiment of the late 1970s. Engineer Eberhard Schulz, who headed the original concept design team, formed Isdera to build his own supercars. 

The 30 examples produced over nine years remained true to the original simple concept. Super-lightweight striking gullwing coachwork on a tubular steel chassis married with outrageous power from the highly regarded Mercedes-Benz 5-litre M119 V8 engine, resulted in unrivalled performance for its time, with a top speed of 275km/h. 

The Isdera marque record was set at $1,340,000 for the unique 1993 Isdera Commendatore 112i at the RM Sotheby’s Paris 2021 sale.
