The Portland International Auto Show is on now at the Oregon Convention Center. Slow sales kept some manufacturers from showing up last year. But this year, they're all here in all shapes and sizes. Greg Remensperger is the show's Executive Vice President ”We’ve got the new Fiat 500; that is first time it’s been on display in the Northwest.; all the way up to the big diesel powered huge pick up trucks.” The auto show's eco-friendly vehicle showcase has expanded to include the Nissan Leaf, the Chevy Volt and other battery-powered or hybrid cars.
