Wow, yet more ignorant and misinformed opinions on GM/Domestics.
Firstly, what you're seeing here is no more than testing. This particular car is already on sale in the M.E. and there are no intentions to market it here in the states. I'm more than sure it's a mule for something GM has in the works, since this is already a Zeta car . Secondly, Holden is no better than Cadillac, they've just been allocated more R&D dollars for RWD development than any of the other GM brands, because that's pretty much all they've worked on all these years, so they have a little more expertise in the matter. Last, Pontiac vehicles will be the only GM NA cars that share the same sheetmetal as Holdens, the new Impala will have an entirely unique design all unto itself.
