As I see it, there is a fundamental flaw in the underlying premise of this entire thread.

A 3D printer can make parts to exacting standards. An ORIGINAL Cobra was a hand built one-of-a-kind with no two cars identical.

You cannot make an identical replica of The AC Cobra, because there was no such thing. They were all different.

You could make a replica of one existing original car, but I would challenge that there are no originals left that are untouched - exactly as they were sold. If you made a replica of a second original, it would be different from the first and so on.
