GM Bankruptcy? To Be or Not?

Almost certain bankruptcy for GM now. Last trade at USD 0.75 . Drop estimated 33% of share value from the last trade day! A BUY or a SELL?
Still remember CITIGROUP INC(NYSE: C) at USD 0.97? Or AIG at USD 0.33? They are like 300- 500% more value then the WORSE time now! Just in the time like within 3 month!
Till now, GM is still working its way out of bankruptcy & looks like it may file for court protection on June 1
Its all depend on the automaker how could they reshape their businesses as they attempt to become viable once again.
Hopefully GM can be cleared a couple of key roadblocks toward the road of "Freedom". Cheers
