GMC C/K

The GMC C/K series served as the brand's primary full-size pickup line from 1960 to 1999, mirroring the Chevrolet C/K. These trucks were built for work, offering a wide range of engine and chassis configurations. Over the decades, they evolved through several generations, but it's the third generation, known as the 'Square Body' (1973-1987), that has become an icon of American truck design.

Collectors are drawn to the C/K's classic styling, simple mechanicals, and versatility. Their straightforward construction makes them easy to maintain and modify, and a massive aftermarket supports everything from period-correct restorations to modern LS swaps and lifted 4x4 builds. The nostalgia for 1970s and 80s pickups fuels a strong desire for clean, well-optioned examples, especially short-bed and 4x4 'K' models.

The market for GMC C/K trucks is robust, with an average sale price around $24,115. While driver-quality trucks and long beds are accessible, prices climb steeply for exceptional vehicles. Restored short-bed 4x4s, particularly from the Square Body era, can fetch prices north of $80,000, showing the high value placed on condition, options, and quality craftsmanship.

Prices range from $5,000 for project trucks to over $83,000 for concours-level restorations and high-end restomods.
