Over at Zero Hedge, they have an informative article up about whether the supposedly successful New GM, otherwise known as Government Motors, is really successful, or whether they are only creating the appearance of success by forcing their dealers to swallow inventory. 

Looks like it's the latter.

  "For a few months there, we were worried that GM may have actually found a (government-funded) natural subprime buyer of its vehicles after the company managed to keep its channel stuffing in check for several months. Those fears ended today with the company's October car sales report, according to which GM sold 4.7% more cars, or 42,759 in absolute terms (from 153,005 to 195,764) in October than September, below expectations of a 7.8% increase. So far so good. What however will hardly get any mention from Government Motors cheerleaders is that GM auto inventory at dealers as of October 31 was a record 739,034 (a massive 98 days of supply), an increase of 49,700 from October's 689,334. In other words, the entire incremental rise in sales, and then some, was due to the firm stuffing dealers with even more inventory than they can possibly handle!"

Full disclosure: one of the family's daily drivers is a GMC, and it's been a great car so far at 140,000 miles.
