It's hard to let a good thing go, especially when it's making money hand over fist. Perhaps that's why Chevrolet is reticent to let go of the long-running Silverado platform. Despite the arrival of the all-new 2007 Silverado, the old model will continue in all its glory, re-badged as the Silverado Classic. Like its twin, the GMC Sierra Classic, the Silverado Classic will continue as a full-line pickup with 1500, 2500 and 3500 models available in Regular Cab, Extended Cab and Crew Cab configurations. Also remaining in the lineup are the Hybrid Silverados, featuring an electric starter motor between the engine and transmission to help save fuel by allowing the engine to shut down when stopped, and the high-performance SS models.
