What car inventory tells you about manufacturing processes

Great graphic from the NYTimes on car inventory in Long Beach port (near LA). Tells you that BMW is the closest to Just in time manufacturing as claimed by them in several articles. They are best managing the current downturn (in terms of inventory on hand).

So if you are in the market to buy a car, this is a great time to get an awesome deal. Inventory of any kind in excess is not good.
