More than one-third (34 percent) of used-vehicle buyers log on the Internet to help them during the shopping process, according to the J.D. Power and Associates 2000 Used StudySM released today. This represents an 8 percentage point increase over 1999 study results when only 26 percent of used-vehicle buyers turned to the Internet. New-vehicle shoppers continue to lead used-vehicle shoppers in Internet usage, 54 percent versus 34 percent, respectively. The study is based on responses from more than 6,000 consumers who recently purchased a 1995 to 2000 model-year used-vehicle.
