On February 19, one of the world’s most desirable pre-war cars, an exceedingly rare 1937 Bugatti Type 57S, will cross the auction block after being hidden for over 50 years.

The auction will take place at Bonhams’ Legends of the Road Sale event. According to the auction house, the Type 57S was originally ordered new by Robert Ropner, a member of the Ropner Shipping Line family, and was custom-built to his specifications by coachbuilding outfit Corsica of London.

The car’s next owner was Rodney Clarke, founder of British Connaught Grand Prix racing team.  It was then purchased by Turnbull, who began its lengthy, multi-decade restoration process in his workshop. Bonhams says the restoration process was nearly complete at the time of his death in 2020, and as such, the car is “only in need of some final re-assembly.” They also mentioned that this Bugatti, chassis number 57503, is in “highly original and excellent condition”, making this a collectors dream.

The car has a 3.3-liter twin-cam engine which was quite powerful for the time.  So much so, that when it was new the Type 57S set a new benchmark for speed and extravagance.

Its chassis is one of the special lightweight versions, made specifically for the famous Bugatti Type 57G “Tank“, of which only three were ever produced, and only one has survived intact. Bonhams believes that one of the missing 57G chassis was re-used for this 1937 Type 57S.

The car has black paintwork, which looks like new.  The original coachwork is still intact, and complemented nicely by the cream leather. It also comes with an extremely well-documented history file, although that’s somewhat expected for a car of this pedigree.

This Type 57S is being auctioned for the very first time, and Sholto Gilbertson, director of Bonhams Motor Cars UK, said: “This really is an extraordinary example of one of the most valuable and desirable pre-war motor cars. Other 57S Bugattis are in museums or known collections… This could well be the last ‘hidden’ pre-war Bugatti of note.”

The classic is estimated to fetch between £5,000,000 and £7,000,000 (USD $6,700,000-$9,400,000).
