Most car companies had a better January than the same month last year, led by Chrysler and GM, which improved their sales 23%.
Ford sales improved 13%. The company had a stronger January a year ago than Chrysler and GM, which were both struggling to rebuild inventories, so Ford's percentage improvement is not as great.
Ford also terminated its Mercury brand in December, and officials say the company is deliberately reducing sales to fleets like rental car companies. A high volume of fleet sales can lower the residual value of a company's vehicles.
