Darrell, I'm just curious, what would you consider to be an non-restored original car? Obviously, if the car is driven, maintenance items would have to have been replaced over the years, etc. Things like plugs, and wires, brakes.
About the closest car I've read about to be completely original and non-restored was the Chevelle that was so original, it still had the original oil and filter. I think I saw pics of it on this site? But about the only was for that to happen is for the car to be stored in a garage new and never driven.
