As I'm sure most of you know, all automakers keep track of their inventories by measuring 'days supply' in the field. They all strive to maintain a 60 day supply in the field and if the supply of a particular model drops below that, they allocate more production or schedule overtime. Can someone tell me where I can get a list of all GM models (especially the VIBE) days supply on the web? I am very interested in the Canadian numbers as well as U.S.A. supply. Thanks.
