The automakers have been hard at work preparing the events that will unveil a slew of new models during the media-only days, which are March 28 and 29.

According to the J.D. Power 2018 U.S. Vehicle Dependability Study, overall vehicle dependability improves 9% from 2017, the first time the industry score has improved since 2013.

The 2018 Chicago Auto Show bills itself as the biggest, much to the chagrin of its neighbor in Detroit and the nation's other big shows in Los Angeles and New York. It is expected to attract one million visitors to the Windy City. That's more than attend the auto show in neighboring Detroit, which drew 809,161 last month.
