@maporsche,
You hope that they will not cease to exist!
The completely car-building infrastructure and supply chains could go belly up in weeks beyond anyone ability to bring them back to life.
Second it the nuts that do not care if the big three exist or not block government loans to the firms once they declared bankruptcy the game is all over.
You do need those funds in or out of bankruptcy and the government look to be the only ones that would provide it to them at any price.
I laugh at what we will be paying for a car after the wonderful Toyota firm is the only real game in town, assuming anyone of us will remain employ and able to buy anything.
We may end up looking like Cuba keeping every car running decades after we should had junk them.
