Chevrolet Advance Design

The Advance Design was a line of trucks marketed by Chevrolet in the forties and fifties. The most popular model was the 3100, also known as the half-ton. They came with inline-sixes, and were marketed as regular pickups, cab-overs, and panel-trucks. "Thriftmaster" and "Loadmaster" models were also available. Originally featuring floor transmission, it was quickly changed to column-mounted. Automatic was available after several years. The line formed inspiration for the HHR five-door and the SSR.
