Los Angeles and Detroit auto shows are tough acts to follow, but the Chicago auto show has proven to be an exciting event with almost 1000 vehicles spread over 1.2 million square feet (40 percent larger than last year). There were certainly a few familiar machines from recent events, but a number of world debuts are worth a close look, including the Dodge Ram Mega Cab and Nitro, Hyundai Portico, International RXT and MXT, Kia Sedona, Mercedes-Benz M-Class, Mercury Mountaineer, Mercury Milan, and Toyota FJ Cruiser.
