As someone with a degree in English, let's play "Antics with Semantics".
A "Clone" by definition is an exact duplicate of the original. (See: 427/435 Corvette).
A "tribute" or "recreation" is a representation of the original, with different levels of concern for details put in or left out. (See: 1969 Z/28).
Both examples exist in greater numbers than GM manufactured, but some fakes are easy to detect, ie "tributes" or "recreations", as opposed to "clones".
The disclosure, or lack there of, is the real difference.
Let the buyer beware. (See: "Barett Jackson").
I hope this helps dispell any misunderstandings.
