If you get the chance to see any Mercedes-Benz 300 SL “Gullwing” coupe up-close, consider yourself lucky as Mercedes only made 1,400 of them. You’re even more fortunate if you own one. To be in the presence of an “Alloy” Gullwing means you are absolutely blessed. Jay Leno knows that feeling: Not only does he have a 1955 Gullwing in his collection, but he also recently had the opportunity to check out an unrestored ’55 alloy model in his garage.

Gullwings aren’t exactly common, but the lightweight alloy versions are much fewer in number. According to Mercedes, between 1954-57, it only made 29 300 SL coupes with aluminum bodies, which were 130 kilograms (286 pounds) lighter than their steel counterparts. In addition, the Leichtmetallausführung (Light Metal Version) of the 300 SL featured a more powerful fuel-injected straight-six engine, sports suspension, Rudge knock-off wheels, and a Plexiglas rear window and side screens, all of which turned it into a sort of “competition” model designed to appeal to privateers and amateur racers.

The Alloy Gullwing you see here was number 26 in the production run and the only one finished in Schwarz (Black) with a Red leather upholstery. Originally configured with a windshield washer system and 3.42:1 rear end, this SL was delivered to Le Mans champion/Ferrari’s North American importer/owner of the North American Racing Team (N.A.R.T.), Luigi Chinetti, according to RM Sotheby’s. Leno said Rudi Klein, a renowned collector and junkyard owner, purchased the car from Chinetti in 1976 for $30,000—a paltry sum compared to its $9,355,000 hammer price at RM Sotheby’s last year.

This SL remained on the grounds of Klein’s Porche Foreign Auto for nearly 50 years largely as it came from the factory. Yes, it was painted silver at one point, and Klein sold some of the attached parts, such as the front bumpers and the shift knob, but the body (minus some forklift damage), interior, engine, gearbox, rear axle, steering box, and front spindles remain original.

It’s too bad Leno didn’t buy this special Gullwing himself because he likely would document its restoration. The good news is that Leno thinks the new owner will restore it and possibly bring it by his garage for a drive, which car fans everywhere look forward to watching.
