When is a genuine Shelby no longer a Shelby

[1985 CCX]

An old friend of mine states:

"The only original is CSX2000 the rest are replicas......"

An original 60's car is always original. I prefer the barn find however many want perfection which these cars were not. Old race cars were re-skinned, re-engined and re-everything. Probably depends upon the car to be honest. A fully restored car can still be a concours perfect car but could be considered overdone compared to 60's standards. Regardless = Original

Now when is a genuine Shelby no longer that, when it never went through Shelby facility is when. Is a car built in SA and shipped to independent dealer in the US for engine and start up a Genuine Shelby?.....................
I would say a 4000 car started at the SAI facility in Vegas = Genuine
My opinion a car that never saw a SAI facility = Hmmmm
Bigger question. Let the games begin..........
