As the economy continues its slow recovery, growing consumer confidence is beginning to be reflected in auto sales. The price-tracking website TrueCar.com announced that 2011 saw the most vehicles sold since 2008, with both new and used cars seeing an increase.

Analysts found that about 12.8 million cars and trucks were sold during the year, which is up significantly compared to last year's figures. Additionally, experts predict that the trend will continue into next year, with J.D. Power and Associates estimating that 2012 will see about 13.7 million units sold.

December was a particularly good month for car sales. Additionally, the website found that there was an 24.4 percent jump compared to November in terms of new-car sales but used models also experienced growth.

"This year was absent of a blockbuster sales month but we see this pace of growth as healthy and sustainable in the coming year where the industry is going to sell nearly 14 million units based on the merits of its products and improved economy," Jesse Toprak, the website's vice president of industry trends and insight.

Certain brands experienced a better final month of the year than others, with Hyundai and Kia selling nearly 40 percent more cars in December 2011 than the previous year. Chrysler had a good month as well, with 33.8 percent higher sales than December 2010.
