One more month, one more chance for GM to stuff its dealers with cars. Sure enough, in the just release January sales PR, the company announced that "General Motors dealers in the United States reported 178,896 total sales in January, a 23-percent increase from a year ago for the company’s four brands. The gain was driven by solid retail sales which were 36 percent higher than a strong January a year ago." And behind the scenes, GM has continued to shove a whopping 510,000 cars with dealers: In January 2011, the firm had 510k cars at its dealers, compared to just 390,000 in January 2010, a 30% increase. Furthermore, as the only component of consumer credit that is surging, non-revolving loans, indicates that virtually all car purchases are made based on the old formula of "no money down." And with the government backstopping both the car maker and the lender banks, we would be very interested in discovering just how bad the delinquency rate in non-revolving car debt is over the past year, especially as it relates to GM.
