When a Nebraska auction house opens its door to buyers later this year for a special sale of vintage cars and trucks, it will be like pulling the lid off of an automotive time capsule.

The auction is taking place at a dealership that closed its doors abruptly 17 years ago -- and hasn't been touched since. It will feature roughly 500 vehicles dating back to the 1950s, some of them brand new and still on the showroom floor, albeit under a thick coat of dust.

"This is a once in a lifetime auction that collectors only dream about -- finding a 'new' old car in a barn," states a write-up on the website for VanDerBrink Auctions LLC.

The auction will take place on Sept. 28 and 29 in Pierce, Neb.

In a video posted on the site, auctioneer Yvette VanDerBrink takes a tour of the dealership, saying "everything is just like it was left -- the parts counters, the parts books, everything."

And tucked in every nook and cranny of the property are vintage cars and trucks -- many of them still with plastic covers on the seats, stickers in the windows and straight-from-the-factory cardboard floor mats.

"We have an assortment of vehicles. The door was shut and they were just left like they are. There's our Impala," VanDerBrink says in the video, pointing to a dusty, full-sized luxury automobile with distinctive lines, crisp red interior and just four miles on the odometer.

There's also a 1958 Cameo pickup truck with just one mile on the odometer, a number of 1957 Chevys, a Corvair and a brand new '78 Corvette, anniversary edition, with just four miles of use. Click here to see a list of the entire inventory.

The collection is the life's work of Ray and Mildred Lambrecht, who operated the Lambrecht Chevrolet Company from 1946 to 1996. Now at 95 and 92, they have decided to liquidate the massive inventory of 500 vehicles, their daughter Jeannie Lambrecht Stillwell explained in a piece detailing the "urban legend" surrounding her parents' dealership.

"The decision to auction the inventory of Lambrecht Chevrolet Company was a difficult and painful one," she wrote. "The collection of over 500 true survivor vehicles comprise a lifetime of hard work, tears, and joy for both of my parents. The dealership today is a virtual time capsule."
