A Mercedes-Benz 540 K Special Roadster (W 29) won the
prestigious “Best of Show” title at the Pebble Beach Concours
d’Elegance 2023 yesterday (Sunday, 20 August 2023). The sporty
luxury car prevailed over a top-class field of exclusive classic cars
in the jury vote at the final event of Pebble Beach Automotive
Week (17 to 20 August 2023). This victory is the tenth “Best of
Show” title for a Mercedes-Benz vehicle since the start of the
Pebble Beach Concours d’Elegance in 1950. This means that
Mercedes-Benz is now the most successful brand in the history of
this crowning event in the classic-car calendar.
The 540 K Special Roadster was originally ordered in May 1937 for Mohammed Zahir Shah, King of
Afghanistan, and delivered in September of the same year. The King opted for a particularly fascinating
product from Mercedes-Benz: the Special Roadster with a Sindelfingen body is a highly elegant sculpture
exuding performance and speed. It is characterised by the high side line of the doors, curved body contours
with a recessed radiator and a flowing rear end with concealed spare wheel. After only five changes of
ownership in seven decades, the current owner purchased the vehicle at auction during the Pebble Beach
Automotive Week in 2022, for $9.9 million.
“The 540 K Special Roadster winning the ‘Best of Show? title at the Pebble Beach Concours d’Elegance
crowns the immense commitment of RM Auto Restoration and Mercedes-Benz Heritage to the restoration
of this outstanding vehicle. We are proud to have contributed to this success story with the unique
expertise of our Classic Centre and the archives. The intensive and good cooperation with RM Auto
Restoration during the past months has made this success possible.”
Marcus Breitschwerdt, Head of Mercedes-Benz Heritage
Restoration with the unique expertise of Mercedes-Benz Heritage
In the months since the auction, the 540 K Special Roadster has been restored to the strictest standards of
authenticity by RM Auto Restoration in close cooperation with the Mercedes-Benz Classic Center. In
addition to the professional support of the experts from Mercedes-Benz Heritage during the work on the
vehicle, detailed documentation of the history of the royal sports car by the Mercedes-Benz Classic
archives in Fellbach played a particularly important role.
This comprehensive know-how also goes into the expert reports by Mercedes-Benz Classic, which are
particularly esteemed worldwide for especially rare and high-quality historic vehicles of the brand: each
expert report is a unique document of originality. It is based on extensive archive research as well as
analyses on the vehicle itself – e.g. the materials used. This is the basis for a detailed description of the
biography of the automobile in question, and a precise assessment of its authenticity. All in all, this creates
a biography of the respective classic that is uniquely authoritative in the classic scene.
Fascinating car biography
The order documentation in the Mercedes-Benz archives and other documents recount the first steps of this
540 K Special Roadster: the exclusive vehicle was ordered by the Afghan royal court in 1937, and delivered
in the autumn of that year. Further history: in the mid-1940s, the French-educated monarch brought the
vehicle to the Afghan embassy in Paris. The supercharged sports car arrived in Great Britain in 1950 as a
gift for his son-in-law, and was sold to a US collector in 1953. Throughout its long and varied history, the
540 K Special Roadster has always been maintained and preserved in authentic condition. To date, the
vehicle has only very few miles on the clock.
The current owner of the vehicle is Jim Patterson. The winners of the “Best of Show” at the Pebble Beach
Concours d’Elegance in 2015 (Isotta Fraschini Tipo 8A Worblaufen Cabriolet, built in 1924) and 2010
(Delage D8 S de Villars Roadster, built in 1933) also come from his collection.
The most recent Mercedes-Benz automobiles as winners of the “Best of Show” award were Arturo and
Deborah Keller’s Mercedes-Benz 540 K Autobahnkurier in 2021 and Bruce McCaw’s Barker-bodied
Mercedes-Benz Type S Touring Car in 2017.
The Untertürkheim plant produced a total of 760 chassis for the 500 K and 540 K models of the W 29 series
between February 1934 and November 1939. 354 had the five-litre engine and 406 the 5.4-litre engine used
from 1936 onwards. Nine body variants were available; they were completed at the Sindelfingen plant’s special
vehicle workshop. About 60 units of the variants with roadster bodywork were produced.
