Automakers End 2012 With Sales at 5-Year High

Automakers on Thursday reported their strongest sales year since 2007, posting solid December results in the United States and promising more growth in 2013.

Sales of new cars and trucks increased 9 percent in December, a gain that put total sales for 2012 at about 14.5 million vehicles — the industry’s best performance in five years, according to the research firm Autodata.

That represents a 13 percent increase over 2011, and raises expectations that demand will continue to rise as more Americans need to replace their aging vehicles with new models.
