CC Is optional on the Silverado W/T base package. Which is basically CC, Key fob and power tailgate lock and window tint. (Current work truck)I'm done with constantly cleaning designer truck wheels, so one of the big draws to me regarding the XL model is the plain Jane metal wheels. But I do like cruise control for open highways and interstates. During a weak moment I once looked at a base Chevrolet Colorado and it didn't have cruise control either. Seems like CC should be standard equipment.
