GM cant compete with market forces and never could, there policy was to buy up trollies n bus systems through out the nation to force people to buy there cars, so for a century they havent been able to compete in a free market and want us to pony up money for them to upgrade so they can compete,,screw em. If you have had a century to figure out how to compete in a free market,,and you still dont get it,,then sell to someone more competent.
