The North American International Auto Show is an automobile exhibition held each year in Detroit, Michigan, known as the Motor City. In addition to presenting cars that will be available to consumers in the upcoming model year, each year dozens of concept vehicles are unveiled during the show. The show runs annually during the final two weeks in January, with the first week reserved for media and industry insiders and the second week open to the public. Since 1976 a black-tie charity ball has taken place on the eve of the public opening of the show. Discuss
