January was an overall down month for U.S. car sales, with the major automakers all reporting declines. Ford  (F - Get Report)  said sales of its cars and trucks fell 0.6% in January. That would have been steeper if it wasn't for sales gains in SUVs and trucks. General Motors  (GM - Get Report)  sales dropped 3.8% last month, and both Fiat Chrysler (FCAU - Get Report) and Toyota's (TM - Get Report) sales fell 11%.

Honda (HMC - Get Report) and Nissan (NSANY)   had sales gains of 6% in January.

January's numbers come after strong sales in December.
