The only silvers offered as standard colors for the 997 are GT and Arctic, however, that really looks like Polar Silver to me, could just be the lighting though.
guyz i dont think this is da carrera 4s...its carrera 4. I dunno why porsche is having da carrera 4s sticker on a carrera 4. A carrera 4s comes with a red line between the rear lights and a turbo front bumper as we all know.. I think they still dont want to reveil the new shape of the carrera 4s since its goin to give a big indication of the 997 turbo shape.. Or is porsche plannin to release the carrera 4s without the turbo bumper? I'd would personally think not..
