People worry to much about that crap! I mean how many people are actually doing a perfect restoration,,, if its not 100% correct is a clone to me.... clones are more popular than originals today and will get more popular as the cost to build continues to go up! There is probably 20 times more of the "others" than "originals"
The cost of actually buying an original, let's say a Challenger T/A or an AAR 'Cuda is prohibitive to buying one. If someone can take a base Challenger/Barracuda and turn it into something that looks like it, then in some ways, you're satisfying your taste for filet mignon with chuck steak for a fraction of the cost... a bonus is that you can also drive the car knowing that it isn't as rare of as the original type of vehicle you replicated and you don't have to baby it as much...
For example...how many replica 427 Shelby Cobras are there on the road now compared to how many were actually built in the 60's? It's very rare/unlikely you'll see an original driving around, especially around Boston...
I guess some people say that you can never have a clone because that means EXACTLY duplicating the car down to the VIN # which you can't (shouldn't) do.
Clone...tribute..., eh, just drive it and enjoy it, don't worry about semantics...
