I found this it says mules already out
"Holden boss Denny Mooney says Camaro mules - jammed in cut-down Holden Commodore bodies - are already on the road in Australia, and the first prototype body-in-white has just been built. Camaro is definitely go.
GM's other Aussie star cars? The little Daewoo-based Chevy T2X crossover concept (third from top with Nick Cannon) was styled by Max Wolff, a Holden designer, and the Chevy WTCC (fourth from top with Mario Lopez) concept - an outlandish take on a European-style road racer - is also the work of a Holden design team.
And finally, there's the Holden Efijy (at left with Christian Slater), a wild re-imagining of the 1953 Holden FJ sedan. The FJ Holden - a car that owes its basic design to a 1940 concept for a small Chevy - is as iconic a car to Aussie GM fans as a '57 Chevy is to their American counterparts. Detroit showgoers may wonder about the Holden badges on the flamboyant Efijy (which was built on a C5 Corvette platform) but there's just enough Detroit DNA in the design that it could be one of the surprise hits of the show.
