Do you know about SB-100?
If not, that's the way to register a Cobra replica in CA and do away with all the grief regarding emissions control.
Take a look at my build: Blown/Injected, registered in 2006 via SB-100, and SMOG EXEMPT for life.

And, as far as purchasing a Shelby continuation car...have you read/searched on that topic? There's more than a few unhappy campers...not regarding the cars in particular; it's more about the company and business practices. In summary, I hope you're not in a hurry.
