The number of cars and light trucks in use in the United States is expected to grow more than 7 percent to a record 234.4 million by mid-2008, predicts R.L. Polk & Co.
Over that period, Polk expects the light-truck population, currently accounting for about 40 percent of all vehicles, to grow by at least 13 percent. The car population is expected to decline by almost 9 percent.
There are two contributing factors: Trucks have been outselling cars, and trucks tend to last longer than cars. By 2008, this trend will shift the country's car/truck ratio from 60/40 percent to about 55/45 percent.
