Holden is one of GM's PROFITABLE companies...
GM is in a bit of strife atm financially, and "word" in the "papers" is saying GM might have to sell holden. But Holden currently has the zeta platform (the VE chassis), in final development stages, GM's future RWD platform after their own fell through. Thats why the new VE will have a deep boot with the petrol tank infront of the rear axle to conform with American safety laws, this means cars can be exported to america, and more exports means more money for Holden.
Holden aint going under anytime soon, they may sellout and get them built elsewhere, but they wont dissapear.
