A couple of points that have not been mentioned here ( as far as I know.)

Holden was recognised by the old GM to be the home of RWD excellence, and the jewel in the GM crown. ( Bob Lutz ?)
If the new GM, not Holden, were genuine about RWD and RHD, Holden would be exporting Commodores, Monaros, Toranas and an unnamed SUV and dual cab ute to the world.

The new GM is not interested in building vehicles, it is interested in profit, share price and subsidies. Australia does not qualify on any of those.
