There was a press release about this back in May
Shelby.com
The wording of the quote from Joe Conway is paraphrased in other articles and would lead one to believe that this is not a street legal car (due to the turnkey nature). I don't believe this is one of the cars produced under the new rules since it would have to use an emissions compliant engine but rather along the lines of the CSX3000 resurrection cars. They will have a MSO and registration for street is your problem
