An updated version of the 1955-1957 classic, the Nomad concept was first shown at the 1999 North American International Auto Show in Detroit. Like its namesake, this Nomad is rear-wheel drive, and gets power from a small-block Chevy engine. The back half of the roof retracts like a venetian blind for the ultimate access and carrying capacity. And of course the rear seats fold, but so does the front passenger seat.
