Few things capture the imagination of car enthusiasts quite like barn finds. That’s because there’s something exciting and mysterious about hearing stories of prized exotics that have been put to pasture for decades.

This particular barn find, coming from the interesting world of Reddit, involves a 1981 Lamborghini Countach with a unique story.

Reddit user ‘eriegin’ says that this white Countach belongs to his grandmother and has been sitting in a garage and collecting dust for roughly 20 years. What’s more, this isn’t an ordinary Countach.

The images posted on Reddit suggest that we are looking at a Countach 500S, one of just 321 examples built. The car is powered by a naturally-aspirated 4.8-liter V12, and while the Redditor claims that it is in poor condition, it could easily be worth $300,000 – or, if restored, more than $500,000.

The Reddit user says that the Countach was purchased by his late grandfather in 1989.

“My late grandpa bought it for his exotic car rental business in 1989, but after insurance costs became too high for him to operate the company, he kept the car (and many others including the Ferrari 308 in front of the Lambo) outside/in leaky garages for 20+ years instead of selling them. Don’t ask me why, I have no clue,” he wrote.

While it’s sad to see a car as iconic as the Countach being locked up for so long, it’s refreshing to see it coming out to the real world again.
