December U.S. auto sales slowed a bit from the brisk pace earlier this year, but automakers still were on target to finish 2013 with the best numbers in six years.

Nissan posted an 11 percent gain for December and Chrysler managed a 6 percent increase. But General Motors, Toyota, Ford and Volkswagen each posted disappointing numbers. Still, most major automakers reported at least a 7 percent increase for 2013, and analysts expect full-year sales to be up around 8 percent to 15.6 million when all the numbers are in. That would be the highest sales figure since 16.1 million in 2007.
