Traffic surged at the 2011 Chicago Auto Show.
The 10-day show, the nation's largest, ended Sunday with an estimated 10 percent increase in attendance from last year's show.
Interest in buying a vehicle, the interactive displays and cooperating weather all played a part in the increase, officials said.
"Our manufacturers and dealers had hoped to see a bump in interest this year, and they weren’t disappointed," said Dave Sloan, the auto show’s general manager, in a written statement.
More than 1,000 cars, SUVs and concept vehicles were on display at McCormick Place.
