1990 GMC C1500 Sierra SLE – 5.7L, Auto, 2WD, A/C, New Two-Tone Paint, Bedliner, Power Windows/Locks, Only 93k Miles! 1990 GMC C1500 Sierra SLE – C/K is a series of trucks that were manufactured by General Motors. Marketed under the Chevrolet and GMC brands, the C/K series included a wide range of vehicles. While most commonly associated with pickup trucks, the model line also included chassis-cab trucks and medium-duty trucks and served as the basis for GM full-size SUVs.

The fourth-generation C/K was introduced in April 1987 for the 1988 model year. The first line not assigned a generational moniker by General Motors, it is known by its GMT400 internal codename. Slightly smaller in cab dimensions than the Rounded Line generation, the fourth-generation C/K increased interior space over its predecessor.

In a branding change, the C/K nomenclature became exclusive to Chevrolet, as all GMC pickups became Sierras (GMC retained the C/K nomenclature for its internal model codes). Chevrolet introduced several specialized variants of the C/K series, including the work-oriented W/T 1500, off-road Z71, and the high-performance 454SS. It is widely known that the 1988-1998 GM Trucks are the hottest trucks on the market and their popularity is well deserved.

After all, they have beautiful styling, great safety and comfort features, and they drive like new vehicles. They have matured to a point where they have are now widely accepted in the world of “classic” vehicles and are welcome entrants to the largest of car shows. What separates the great C/K examples today from the thousands of trucks produced are those with lower miles and/or that have been well maintained over the last 30+/- years.

Locating well maintained examples such as this beautiful 1990 Sierra is getting harder and harder! The interior, engine, paint and tires are all in excellent overall condition. We have noted a few small dash cracks and minor paint chips that have been touched-up. Overall, a much nicer truck
