Restructuring is what GM NEEDS TO DO in order to survive. The Chinese cars arrive for the 2010 model year. No one will want a ( base)cheap GM, Ford or Mopar car for 12 grand when they can buy a Chery or Geely for 8 grand brand new with warranty. Only way to save, not put off certain death but actually save the big three will be file, fire, restructure and come back WAY leaner on the cost of production side to compete. As for GM engines, wj\ho really cares. World and Dart make blocks, heads, lots of crank and cam manufacturers etc. No foreseeable supply problems there.
