 Chevrolet Silverado Intimidator SS
Chevrolet Silverado Intimidator SSAlthough General Motors introduced its first pickup truck in 1930, the term "Silverado" was a designation used only to detail the level trim for the Chevrolet C/K  pickup trucks and Suburbans from 1975 through 1999. GMC used a few  variations of the "Sierra" name (Sierra, High Sierra, Sierra Grande,  Sierra Classic) to distinguish the different trim levels through 1987,  though the "C/K" nomenclature was continued through 1999. "C" (or "R"  for 1987) trucks had rear-wheel drive while "K" (or "V" in 1987) models had four-wheel drive.  Both Chevrolet and GMC dropped the "C" and "K" designations in 1999.  However Chevrolet still uses the CK and the CC in their current model  codes.
The Chevrolet Silverado and GMC Sierra trucks have been essentially  the same for their entire history. The Silverado today is generally  advertised as the "lower" version, while the Sierra has more luxury  options. There are some trim and option variations as well. Early models  included variations in the engine and equipment, but the present  differences are slight. The 1999 redesign included different grilles and  interior trim, and certain features (e.g. Quadrasteer) were included at different times on the two trucks.
