Mercedes-Benz 280 SE 3.5 Cabriolet 53-Year-Old Has Never Been Restored

If you thought we’d reached peak absurdity with sky-high classic car prices, think again. Enter this 1971 Mercedes-Benz 280 SE 3.5 Cabriolet, a car so meticulously preserved that it might as well come with a time machine set to 1971. It could fetch up to $1 million at an auction next week, or double what a similar 280 SE 3.5 Cabriolet sold for at Monterey Car Week in 2023.
 

According to RM Sotheby’s, the auction house wielding the gavel on this slice of German perfection, it’s “one of the finest examples in existence.” Translation? If you’ve got a million bucks burning a hole in your pocket, congratulations—this car could be yours to park, polish, and definitely not drive.
 
Even though it’s more than 50 years old, this Mercedes retains its original engine and transmission. What’s more, the exterior is completely original, the interior has been left untouched, and even the folding fabric roof is exactly as it was when it left the factory.
 

The car was purchased new from a dealership in Colorado and the first owners kept it until 1987, never once lowering the roof. In 1987, it was purchased by Mercedes-Benz collector Karl Keller who kept it for 16 years and only ever drove it 500 miles (805 km). It was again sold in 2003, and in 2008, the new owner had it serviced and a new exhaust system fitted at a cost of $29,000. In 2014, it was sold again, and in 2022, it came into the possession of the current seller, where it has resided in Southern California alongside a 300 SL Gullwing.
 
What’s particularly remarkable about the classic Mercedes is that it has never been restored, and yet, it looks as good as new. Mercedes-Benz only ever produced 1,232 280 SE 3.5 Cabriolet models, and just 347 for 1971, the car’s final model year. It’s powered by a 3.5-liter naturally-aspirated V8 that delivered around 200 hp back in the day alongside 210 lb-ft (285 Nm) of torque.
 

All up, this classic Mercedes has racked up just 20,192 miles (32,495 kilometers) since 1971—a laughably low figure for something that’s over five decades old. That’s barely 400 miles a year, or roughly the distance many people cover over a long-weekend trip. But then again, this isn’t a car for racking up highway miles. It’s a car for pulling up slowly to a Beverly Hills valet stand, where everyone pretends not to notice while sneaking a second glance.
 
So, if your love for German engineering, 1970s nostalgia, and aggressively pristine upholstery outweighs your financial common sense, head over to the listing and prepare to outbid your fellow collectors. Just don’t forget to keep that roof up—it’s tradition.
