DETROIT -- General Motors said Tuesday that its U.S. new-car and truck sales in March fell 3 percent to 391,752 vehicles after the U.S.-led war with Iraq and the struggling U.S. economy weighed on consumer confidence.
GM said car sales fell 5.3 percent to 165,166 units, while truck sales dropped 1.2 percent to 226,586. The results include GM's Saab unit and some medium- and heavy-duty trucks.
Earlier Tuesday, Ford Motor Co. reported a 4.8 percent drop in its March sales, excluding its foreign brands and some medium- and heavy-duty trucks.
GM also left unchanged its second-quarter new car and truck production estimate for North America.
To try to spur sales, GM unveiled late Monday what it called its most aggressive incentive plan ever, interest-free financing for five years on almost every vehicle it sells. GM's top sales official said Monday that its strong offer is the right catalyst to spark sales.
