Hard to believe, but these things still crop up with extremely low mileage and near perfect condition; it's very possible everything listed about the car was close to the mark.
A good friend of mine some years back uncovered a less-than-7000 mile '68 SS, a Corvette Bronze car, black interior, just unbelieveable condition, featured in several books and magazines (Hooper's is one). He should have left it strictly alone, but touched up the paint and striping and chrome in a couple of areas, and rebuilt the drivetrain. Car has since been sold several times, last I saw it was in Canada. Tough to think about paint touch up on a 100% original paint car, but at least the guy painting it is renowned for what he does. Car could have turned many survivor class cars on their ears had he left it alone -
I agree with the possibilty of "listing errors" being "fee ducking". Seen it happen more than a few times -
