I think Jim Wallis is right on with his response to this Public Apology to the Public from GM:
While we’re still the U.S. sales leader, we acknowledge we have disappointed you. At times we violated your trust by letting our quality fall below industry standards and our designs become lackluster. We proliferated our brands and dealer network to the point where we lost adequate focus on our core U.S. market. We also biased our product mix toward pickup trucks and SUVs. And we made commitments to compensation plans that have proven to be unsustainable in today’s globally competitive industry. We have paid dearly for these decisions, learned from them and are working hard to correct them by restructuring our U.S. business to be viable for the long-term.
