There are imperfections from the factory in every car. Welds were done by hand in 1976. Repairs were done by hand. I wonder what improbable similarities the 2 cars could have.
The car would be authentic, built in 1967. What the person is asking is whether there's a technique to distinguish a car from 1967 from a sibling that was brought back from 2036.
Let's say there was a Corvette made in 1967. Let's say that in the 2030's, John Titor brought it back to the past. Let's say we found this car because it had a duplicate VIN number.
Then if we put the 2 cars side-by-side, we should be able to tell if one is a re-VINed stolen car, or if they are both the same car.
I suggested we look at welds that were done by hand in 1967 to determine if the 2 cars were the same car.
