I voted hell yes and I will explain why....
I don't have enough knowledge regarding the economics of it all but it would be like Paradigm Shift forced by other factors,
like a Revolution of sorts.
Example:
Much like film became obselete when digital cameras hit the scene and Kodak workers where sacked.
Sad for the workers, but we all rejoiced in this technology at the time and still do!
I would imagine that same kind of excitement if it eventuated and we can pick up any car from around the world
brand new for half price.
In this case I could give less than a stuff about Ford, Holden or any company that has making good money of us.
They have had it all to themselves for ever and now the time has come and we have front row seats to witness
this transformation.
They too will need to step up and compete and make the GT335 $24999, YEAH!
If they can't do that, then we will have no choice but to buy M3s, Skylines etc... as the
op said.
But, it's another bloody hypopathetical
