A Kansas businessman kept his enormous collection of classic cars hidden away for close to 30 years. Now, that secret stash of Americana — including several highly collectible Corvettes — will be auctioned off.

The vast collection of more than 140 cars belonged to the late Bob Regehr, an inventor and entrepreneur whose claim to fame was inventing the bounce-house castle back in the 1970s. A lifelong car enthusiast, Regehr started collecting cars when he was just 14 years old and eventually amassed a whopping 226 vehicles, his daughter told local outlet KWCH.

Regehr apparently had a thing for antique cars — much of the collection dates back to the 1920s, 1930s, and 1940s — but he also snatched up plenty of iconic sports cars from the '50s, '60s, and '70s. Some of the most notable models hint at his affinity for Corvettes, of which he had eight.

The entire collection — originally dug up by Carscoops — will cross the auction block on October 24 through VanDerBrink Auctions. But before then, take a closer look at his eight stunning, long-hidden Corvettes:
