Well all you have to do to find out what new GM fast car is going to hit the states, just check out Australians Holden line, the GTO, G8, Camaro, Cruze,Regal,
Caprice are all Holden's just de-tuned and re-badged to be an american Version.
And yes the Camaro is being built here in the US at the same plant they used to make the Monte Carlo, but it was based off of the Holden designs for a new Monaro (GTO).
You want to see the really fast version of the cars just google "Holden HSV" and you see what im talking about. It take an Australian to make an American Muscle Car now days.
