GM is trying to find a way to separate the credit rating for General Motors Acceptance Corporation. GMAC, GM's financial arm, is the main money maker for GM and financially in much better shape than GM. GM wants to ensure that the S&P "junk" rating given to the automotive division does not harm the financial performance of the healthy GMAC. We see this as the first step in separating the two. After all, isn't that what Kerkorian really wants.
