The automobile market in the U.S. showed strong sales for Chrysler, Ford and GM in November 2011. As a result automakers expect to sell 12.7 million vehicles in 2011, 10% higher than 2010. The average age of vehicles in the U.S. is 11 years, and this is leading to more buyers coming into showrooms. Some of this demand was for prickup trucks and SUV's. Ford Explorer sales tripled from the prior year. Ford sold 26% more trucks and 9% less cars compared to the prior year November sales. Sales of Jeeps went up 50%. GM sold 31% more pickup trucks. In the past sales of trucks and SUV's slumped with rising fuel prices and a slower economy.
