While GM sales were down 13 percent in the U.S. in January, due to a 58 percent reduction in daily rental volume, truck sales were up 10 percent over last year, midsize utilities were up 50 percent and full-size pickup sales were up 20 percent. “We had a phenomenal year in truck sales in 2001, setting several truck sales records, and we continued that momentum in January,” said Bill Lovejoy, group vice president of North America VSSM.
