For whatever reason many of the experts are completely ignoring the Ten Ton Elephant that is sitting in the room. You guys ABSOLUTELY know that almost every restored vehicle out there has almost NO remaining original parts BUT are "authenticated" by the original Build sheet. In past threads you have preached how a car "can only be original once" and a restored car should NEVER rank over an all original one. But NOW you want to pull back from that position when the Build sheet comes into play. NOW the build sheet actually DOES make a reproduction, non-original car worth more. WITHOUT the Build sheet a "reproduction car" is nothing but a reproduction "fake" car. WITH the build sheet it is magically transformed into representing and authenticating an "all original vehicle". If not for absence of linear logic or rational thought, I would think all of this as nothing more than a bad punchline to an Automotive joke!
