Nice car with cool colors and evidently the original drivetrain, although the seller didn't post the stamps in the auction (but offered to text pics to interested buyers).
I'm thinking $70k is close to all the money for a '70 Z in this market - and this is one of those cars I'd love to own if the market cools a bit. I had a '70 SS years ago that was a total blast to drive, and a pretty good handler compared to the first-gen cars.
