You now have the chance to completely restore what many consider to be the greatest sports car ever.

A 1956 Mercedes-Benz 300 SL ‘Gullwing’ is heading to auction via Artcurial, where it could snag $6 million when it goes under the hammer. This example of the car also has the advantage (or disadvantage, depending on your perspective) of being completely unrestored. Buy this car, fix it up, and one day you might win at a concours event.

This iteration is one of just 30 300 SLs that were delivered to France, according to the auctioneers. The car was ordered new in January 1956 “with all the sports options available in the catalogue at the time” by its first owner, a Paris industrialist named Claude Foussier. Foussier later sold the car in 1961, and it changed hands again that year, passing along to an owner who kept it for decades. That owner then sold the 300 SL in 2014, after a period of neglect.

Still, according to Artcurial, “On the day it was collected, the car had not run for 11 years. It was covered in a thick layer of dust and the tyres were flat. Despite this, it needed only six new spark plugs, a battery and a bit of fuel to start it up and load it onto the buyer’s trailer, to head off to Germany.”

A couple more owners later, and the 300 SL headed back to Paris in what seems like an extraordinary coincidence.

“Recent research with the city authorities have shown that Claude Foussier, the first owner, lived at 2 boulevard Suchet,” Artcurial says in its listing. “A surreal coincidence … the same address, believe it or not, as the current owner’s home, and today the car lies at rest in the same garage as in 1956! What is the probability of the car ending up at the same address, 70 years later, as that of its first owner?!”

Under the hood is 3.0-liter six-cylinder engine mated to a four-speed manual transmission that, originally, produced around 235 horsepower. Just 60 300 SLs of this particular specification were built, including performance aspects like an upgraded suspension, wheels, and engine with racing in mind.

Dust also still sits on the car, as the photos make evident, including the seats, which have never been cleaned, and the paintwork, which is all original. The car has a bright future, though, destined for the eyes of admirers.

“We can already state that the car and its new owner will be invited to the next Concours d’Elégance at Chantilly,” Artcurial says. The auction house estimates that the car will fetch between 2 million and 5 million euros (around $2.2 million and $5.8 million) at auction, which will take place on January 27 in Paris.
