Seventeen years ago, Ray Lambrecht decided to close his Chevrolet dealership in a small town in northeastern Nebraska. However, when he shut the doors, the lot was not empty. For decades the owner had been stockpiling old Chevy cars and trucks that didn't sell right away. He stashed them all in a warehouse, at his farm and other spots around the town where he worked for more than 50 years. Now he's ready to auction off these classic beauties for a handsome profit.

About 500 classic Chevy models sit relatively untouched in Lambrecht's lot. Next month, visitors will gather to the small town of Pierce Nebraska, home of only 1,800 residents, to bid on the cars, some of which have fewer than 20 miles on the odometer.

Some of the Chevy cars and trucks in his metaphorical garage are so rare that there is no set price for them, they'll just end up going to the highest bidder. The most valuable car in Lambrecht's collection is a rare Chevy Cameo pickup truck. The car is expected to fetch a six-figure bid from collectors who "view them as works of art to display or as restoration projects," according to the Associated Press via Fox News.

The auction will take place over the course of two days. Cars will go on the auction block as-is.

"To find this many new, old vehicles is unheard of," said Yvette VanDerBrink, the auctioneer coordinating the event. "It's like a white buffalo."

The prep work for the auction has been going on since June with VanDerBrink taking calls from Iceland, Singapore and Brazil. The two least driven cars include a 1960 Corvair Monza and a 1959 Bel Air, each with only one mile on the odometer. The oldest vehicle, which fewer than 20 mils on it, dates back to 1958 and the newest is a 1980 Monza with only nine miles on it.

Chevy and classic-car enthusiasts have one month to get their affairs in order to head to Nebraska, or bid online, to have a chance at taking home one of these barely used classic bits of American history.
