That is a bad sign...maybe very bad...but zerohedge is a little wobbly on this issue as they are only tracking post bankruptcy GM in some of their studies.
They cherry picked their starting point at the bottom of the recession (though that is new GM). Back in July '06, old GM's dealer inventory was over 1,000,000. Also, pretty sure GM was over 100 days just before junk hit the fan in '07/08.
Point well taken though...and stunning visualization.
