Updated from 12:29 p.m. ESTGeneral Motors ( GM) and Ford ( F) wrapped up 2007 with another month of U.S. sales declines, ending a dreary year for the automakers as each grappled with a consumer slowdown, soaring oil prices and tough competition. With the declines from Detroit, Japan's Toyota Motor ( TM) surpassed Ford as the nation's No. 2 automaker for the year. For December, GM's U.S. light-vehicle sales fell 4.4% to 319,837 units. Car sales tumbled 10% to 116,583 vehicles, partly reflecting a plan to cut lower-margin sales to rental firms. Light-truck sales, meanwhile, fell 0.8% to 203,254 trucks. For all of 2007, GM recorded a 6% drop in U.S. sales to 3.82 million vehicles. Ford, meanwhile, posted a 9.2% drop in December sales to 212,094 vehicles. Truck sales tumbled 9.5% to 147,443 vehicles, and car sales sank 8.4% to 64,651 units. Retail sales dropped 13% for the month, while fleet sales were down 1%. Toyota surpassed Ford for the month with sales of 224,399 vehicles. While that was a decrease of 1.7% from a year earlier, the results were enough to make the Japanese giant the year's No. 2 automaker in the U.S. -- a position that Ford had held since 1931, according to the Associated Press. Toyota ended the year with U.S. sales of 2.62 million vehicles, a 2% rise from a year earlier. Ford's domestic sales for 2007 slid 12% to 2.57 million vehicles.
