Attendance at the the North American International Auto Show in Downtown Detroit reached an 11-year high.

More than 800,000 people attended the show, which wrapped up Sunday night.

Bob Shuman, chairman of the auto show, said the event helps boost the economy.

"The economists tell us that it brings $365 million in economic activity to the metro Detroit area," he said. "That's like a Super Bowl every year in the city of Detroit. It's very important to our economy. It's very important to our future, to our culture and our society here."
