We all know the importance of a build sheet. Thinking of the future, do MODERN cars (like a 2021 Shelby) come with a build sheet? How would we authenticate that car as a Shelby 40-50 years from now (when they don't use gas anymore)?
Sort of. But not like they used to be. Here is some info;

Marti has access to the Ford database for years 1967 to 2017 . He will probably push those dates as time warrants.
You might get a build sheet on a factory Ford product, but probably not from something made from Shelby American Las Vegas or any other Shelby licensed vehicle producer to verify assembly. 8)
