The aluminium-bodied coupe is one of just 28 'Alloy' Gullwings in existence.
A 1955 Mercedes-Benz 300SL ‘Gullwing’ has sold at auction for $US6.85 million ($AU9.5 million) in the USA.
The two-seater – stamped chassis number 5500332 – is one of just 28 examples ever built by Mercedes-Benz with an aluminium body, which was designed to shed weight and improve handling in competition.
The original number-matched 158kW/294Nm 3.0-litre straight-six petrol engine is retained, however the blue gabardine fabric upholstery and four-speed manual transmission were swapped out during a 1979 restoration.
