Robust U.S. auto sales have been helping to keep a floor on the U.S. economy for months, and they kept up the good work in June.
Car sales surpassed the expectations of many analysts.
The good news included Detroit car companies. Ford sales rose 7% and Chrysler sales jumped 20% compared to June a year ago.
General Motors sales increased nearly 16%.
GM's Kurt McNeil says he expects a good second half of the year, too.
