Well if you pay attention to automotive news you may have heard about the sinkhole that swallowed 8 historic Corvettes in the National Corvette Museum. Well yesterday they hauled out the last one and it's planned for a short time to display them as is and later send them to GM for restoration. Unfortunately I personally don't think that's possible with half of them. The "Blue Devil" ZR1, 1962 Corvette, 1993 40th Anniversary, and the 1,000,000th Corvettes were fished out with minimal damage to them,

they were able to start up the ZR1 after it was hauled out. The other four though, the PPG Pace Car, ZR1 Spyder concept, the 1,500,000th, and Mallet Hammer Corvettes, I honestly can't say they can be saved and are unfortunately destined for a junkyard. The only way I can see for these cars to be seen again is to try and salvage the VIN numbers off them and rebuild them from existing Corvettes.
