GM has axed lifetime benefits for former employees. As I understand it, these benefits were one of the factors that may have contributed to the auto industry's downfall, paying benefits to workers well beyond their tenure. Sucks for the former employees who now have to scramble but this was probably necessary. It's not going to save the company though, they're just trying to stay alive at this point.
I've also heard a report that Chrysler may be 'broken up' and sold off as smaller parts. That probably means someone will buy the Jeep name, Sprinter will go somewhere else, etc. Who knows.
Hopefully Mopar Performance will still be around in some capacity.
