IIRC, the GMPP is actually financially backed by GMAC insurance. So, unless GMAC Insurance is rolled into the BK, I THINK anyone with a GMPP will be ok.Excellent question. I too, would like the answer.
My guess is that anyone that bought GM/GMPP's assets would assume the liabilities as well (warranty/service contracts).
Got 3 GMPP contracts in affect right now myself.
