Note: in September 2009 U.S. light vehicle sales were 9.3 million (SAAR). There was a sharp decline in sales following the "Cash-for-clunkers" program that ended in August 2009, so the year-over-year comparisons look good. The real key is the seasonally adjusted sales rate compared to the last few months (total U.S. light vehicle sales have been mostly flat since March 2010).

From MarketWatch: GM September U.S. sales up 10.5% to 173,155 units

General Motors Co. said Friday that U.S. sales in September rose 10.5% to 173,155 vehicles from 156,673 in September 2009.

I'll add reports from the other major auto companies as updates to this post.

Update1: from MarketWatch: Chrysler U.S. September sales surge 61% to 100,077

Update2: from MarketWatch: Ford U.S. Sept. sales jump 46.3% to 160,873 units

Update3: from MarketWatch: Toyota U.S. Sept. sales rise 16.8% to 147,162

NOTE: Once all the reports are released, I'll post a graph of the estimated total September light vehicle sales (SAAR: seasonally adjusted annual rate) - usually around 4 PM ET. Most estimates are for an increase to 11.6 million SAAR in September from the 11.44 million SAAR in August.
