All three of these companies have to deal with the problems at both ends. They need to start at the top and the bottom, and get back to building quality cars that will turn a profit.
Right now I feel like GM has the best new product offerings, but obviously they're in the worst shape financially. Ford took out a large line of credit earlier so they're OK for a while even without the Federal loans. I can see both of them returning to viability, but Chrysler seems like a lame duck with very little hope.
