The granddaddy of all musclecars: The SS. In the past, the "SS" moniker was liberally applied to everything from big-block Chevelles and Camaros to puny front-wheel drive boxes with decal packages. Most folks will relate to the former, and thankfully the 2003 SS concept hearkens back to them as well. The best sign SS could make production is its four-door layout. A concession to practicality, extra doors may well be the purchase justification needed for brow-beaten husbands everywhere.
