"Consumers continued to opt for less expensive cars in the fourth quarter, even as auto loan rates rose and the national recovery gradually reaccelerated," said Dana Johnson, Chief Economist at Comerica Bank.  "The average interest rates on auto loans rose to 4.6 percent, the highest since the first quarter of 2009.  Looking ahead, affordability could erode as the cost of financing a new car increases due to rising interest rates."
