A 1955 Mercedes-Benz 300 SLR Coupé Sells for Record $142 Million to Benefit Charitable Fund

A road-racing car built by Mercedes-Benz in 1955 and kept by them ever since has been secured by British expert Simon Kidston for a client. Kidston had lobbied the board of the German company for 18 months to consider selling the car “that would never be sold”.

In an invitation-only event held at short notice in conditions of great secrecy at the Mercedes-Benz Museum in Stuttgart on 5 May 2022, Kidston’s bid of €135m secured the car for an unnamed collector. Mercedes-Benz will use all monies to set up a charitable fund for young people.

It had always been assumed that Mercedes would never part with one of the crown jewels of its company collection, considered the ‘Mona Lisa’ of cars, because of its rarity, racing pedigree, beauty and unavailability. The final figure of €135 million (c.US$142 million on the day) smashes the existing record for the sale of a car, believed to stand at $78 million in a private sale of a 1962 Ferrari 250 GTO, which took place in 2018.

The 1955 Mercedes-Benz 300 SLR Coupé developed the open two-seat sports-racing car built by Mercedes for the 1955 season and driven by Grand Prix greats such as Stirling Moss, Juan Manuel Fangio, and Peter Collins.

Heavily based on the company’s all-conquering W196 Grand Prix single-seater, a 302bhp powered the W196 S sports car, a 3.0-litre straight-eight of great complexity that dominated the 1955 World Sportscar Championship. Moss’s record drive on the 1955 Mille Miglia has been described as one of the greatest-ever feats of motor racing.

Dual-nationality (German and British) engineer and chief of Daimler-Benz motorsport Rudolf ‘Rudi’ Uhlenhaut commissioned two closed versions of the dominant sports car for endurance racing use. The design shares styling cues with the famous 300 SL ‘Gullwing’ road car but under the skin is a pure competition car with almost no concession to practicality, as none was ever intended to be sold to private clients.

Neither 300 SLR Coupé was raced, though they were used for practice and as highly skilled drivers of Uhlenhaut’s high-speed transport to European events. A road test jointly conducted by British magazine Autocar and Swiss periodical Automobil Revue in 1956 produced the following figures: 0-60mph 6.9sec; 0-120mph in 20.3sec; maximum speed 176.47mph. For the road test, the car was fitted with power-sapping silencers.

“Remember that this car is not for sale, and in this form never will be: it is a racing car adapted for road use with certain experimental objectives in view… It has to be mastered like a spirited horse.”

“To have driven it has eclipsed all previous experiences in 20 years of test driving on the world’s finest cars, and I do not expect to find its match for a long time to come.” Writing for British magazine Autocar in January 1957, Gordon Wilkins describes the other-worldly capabilities of the SLR Coupé.

Commenting on the record transaction, Kidston said:

“If you had asked classic car experts and top collectors over the past half a century to name the most desirable car in the world, there’s a good chance that they would have come up with the same model: the Mercedes-Benz 300 SLR. It’s a combination of exotic engineering, all-conquering racing history, the power of the three-pointed star on its nose, and the fact that one had never been sold. Many collectors had tried, but all had failed.

“That was what the entire motoring world thought, but times change, and you’ll never know if you don’t ask. A long-standing relationship with the Mercedes-Benz Museum helped. Still, even after 18 months of patient lobbying, we didn’t know if or how they would consider letting the 300 SLR out of captivity until just before it happened. For everyone involved, especially the new owner we represented, this was a once-in-a-lifetime chance to buy the Mona Lisa of cars.”
