[VIDEO] Two C3 Corvettes Stored Outside for Decades Get Cleaned Up in Advance of Being Auctioned

Hidden beneath failing tarps and decades of grime are two classic Corvettes that haven’t seen the road in more than 30 years. In a new YouTube video, the guys at Demolition Garage get the keys—well, sort of—and begin the journey of unveiling their stories, cleaning them up, and preparing them for auction and their new owners.

DG’s client inherited these vintage C3s when his father passed away. They’ve been stored outdoors for decades, and it shows in their condition. Neglected under makeshift covers and even bricks, they’ve endured harsh sun, tree sap, and creeping foliage. Now, with the estate settling, it’s DG’s chance to move them onto a transport and into the light.

The first car is a yellow 1969 Stingray convertible (with a matching hardtop) powered by a 427/390 horsepower engine, or at least that’s what DG hopes. Because the hood can’t be opened since it’s frozen in place, all he knows is that there is some kind of engine underneath.

He’s surprised to find that an initial pass with a pressure washer reveals decent paint, though he’s not really interested in full detailing – just making them presentable for prospective buyers. A non-factory repaint in yellow is identified after the cleaning, based on the overspray underneath, and that could factor into its auction value. Still, it’s amazing how good the car looks, at least on video.

Up next is a silver 1975 Corvette T-top coupe with the more desirable L82 option (mistakenly called an L88 by the video host). They can’t even get into the car because they don’t have the keys, and their efforts to jimmy a door open fail. Surprisingly, though, the silver paint looks halfway decent after cleaning, other than the rear deck where it comes loose in spots.

These Corvettes deserve a second life. By the end of the video, DG has taken them from forgotten barn finds to cleaned canvases ready for passionate collectors to make their mark.

Soon they should be rolling down the road again, hopefully never to get this nasty again!

You can clean those cars all you want but that ain’t gonna help the birdcage and frame underneath that’s most likely rusted out from being exposed to all the moisture over that many years.

The silver one is a 1977.

Agreed. Silver Corvette is 1977. They dropped the Stingray name that year and stopped writing it on the body panels which was replaced by the Corvette logo.

So who are the “experts” who don’t know or can’t tell that one vette is 1977 not 75 ??
