I've personally seen them in white, red, blue, and silver. Factory paint. Watched a red short bed GT get picked up by a claw and put on a flatbed trailer to go to the crusher. They wouldn't sell it to me, and I tried for years to get it..
It was in a local man's personal junkyard of around 500+ cars/trucks, and he was one of those guys that wouldn't ever sell anything. The state ended up coming down on him with the EPA and 99% of his personal junkyard went to the crusher. Chevelle's, Nova's, Camaro's, Fairlane's, Toronado's, Galaxy's, Ranchero's, early Ford, Chevy, Studebaker and International pickups, every cool car I ever loved growing up. ALL CRUSHED because the old man was a dumbass and never wanted to sell anything, so once the state got involved, none of the cars could be sold. All had to be crushed based on a court agreement.
He could have easily been dragging them in, reselling them at a nice profit, been loaded down with cash, and kept dragging in more of them, but nooo.. Instead he lived in an old run down house with the windows knocked out and part of the roof caving in, and he still lost his entire collection.
