Marchionne puts the squeeze on GM; GM's response: 'Why bail out FCA?'

DETROIT -- General Motors has flatly rejected the advances of its crosstown rival, Fiat Chrysler Automobiles, but FCA CEO Sergio Marchionne is not going away -- not by a long shot.

Marchionne says he has sweated the details and done the math and discovered there's far too much upside in a merger of FCA and GM to let a deal go undone, or at least unexplored.
