A customer of mine has an original 1969 Camaro SS350 that he is restoring. It is a very nice car, and has all the details and numbers just perfect. His best friend has a stunning 1967 Chevelle SS427. The Camaro is a stock resto, but the Chevelle is mildly built. It has Centerlines on it, but it looks like it came that way. It's a very well done fake. It has all the Super Sport emblems, including 1967 SS427 front and rear badges. It really has a 427 in it, too, but it's still a fake.
He doesn't ever tell anyone that it's real, but when kids drool over it at the gas station, he just lets them think whatever they want. If they were to ask, he'd tell them the truth, but he doesn't have signs on the doors saying "This car is a fake". That would defeat the purpose. he put a lot of time and money into it, and it shows.
Which one would I rather have? The Chevelle. The Camaro is worth more, but the Chevelle is a daily driver, if you want it to be, without any concerns.
As long as it looks good as a practical package, and you don't try to pass it off as an original, I see nothing wrong with it. If the Chevelle I just told you about was a four door, I would be very much against the idea.
Make sense?
Take care,
