  • A rare Mercedes convertible that had been parked in an Indiana warehouse for more than 40 years just sold for nearly $1.1 million.

  • The car, a 1960 300SL Roadster, is one of the hottest collectibles in the classic-car world today, and they rarely go for less than seven figures.

  • The Roadster was purchased by its previous owner in 1976 and was tucked away soon after, so it shows less than 15,000 miles on the odometer.

  • It's one of only 249 300SL Roadsters built for 1960, according to the dealership that sold it, making it an exceedingly rare car.

A Midwesterner's ultra-rare Mercedes-Benz 300SL Roadster that had been hidden away for more than 40 years just sold for more than $1 million.

Seven figures is undeniably a huge sum for what looks like a dusty old sports car, but this isn't just any dusty old sports car.

In today's classic-car market, the 300SL Roadster and its Gullwing sibling are two of the hottest collectibles money can buy. All in all, Mercedes only built 1,848 Roadsters between 1957 and 1963, and the Roadster that just sold is one of only 249 produced for the 1960 model year, according to the dealership that sold it.

They generally go for at least $1 million at auction, and untouched "survivor" cars like this one can be even more prized than restorations. That's why it doesn't come as a surprise that after the car was listed by New York-based classic-car dealership Gullwing Motor Cars for $1.095 million, the dealership confirmed to Business Insider that it went for the full asking price.

Besides being tucked away in a barn for four decades, this particular 300SL Roadster came with low miles and a known ownership history, making it particularly valuable.
