How about this: 2 identical cars...survivors lets say...priced the same...one with, one without...both legit cars...Which one would you buy?
Difficult to answer. On the surface the car with the build sheet would win. However, other documentation including a continuous chain of ownership and documented history from new is worth quite a bit. Maybe you just like the "feel" of the car without the sheet, or the way it drives.
The build sheet is not the ONLY factor to consider when evaluating the legitimacy of a car. But it is very relevant, particularly in the more high end Mopars. With few exceptions, a high end car without an original build sheet probably gets some kind of a haircut price-wise compared to one that does.
Different marques of cars have different ways of evaulating the provenance of their cars. My Mercury Cyclone Spoiler II had no build sheet (most of them don't). Fortunately, we have Kevin Marti and his access to the Ford warranty database to tell us more than we need to know about the car. In the case of Mopars, since we don't have that information available, the build sheet becomes a more important component to us That said, I see no reason to throw another wrinkle into the process with reproduction sheets.
