Shelby makes parts. He might fasten some parts together, but he does not make cars in a way that they are legally cars by today's standards.

I don't think Shelby is listed as a "Manufacturer" like Saleen so Shelby does not make cars. (I could be wrong about this and maybe Shelby is listed as a "Manufacturer")

As far as I know to title/register and inspect a component car in the USA it is not supposed to be manufactured by anyone other than yourself unless you bought it off a fellow that built it for himself and then sold it. Of course this opens up a big gray area as to what "manufacture" means and if anyone really wanted to push the limits of the laws, we would probably find out that a lot of the businesses making complete rollers that only need engines and transmissions are not at all what the legislators were signing up for when approving these laws, and the bigger that part of the business gets, the more likely the rest of the hobby is to suffer in the long run.

Keep in mind this is all my opinion and I am not trying to write this in an explosive fashion.
