Model History: The 1987 GMC Sierra Classic represents the final evolution of General Motors' iconic square-body truck design, which debuted in 1973 and became synonymous with American work truck capability. By 1987, GM had refined this platform through nearly fifteen years of development, incorporating lessons learned from both commercial and consumer feedback. The Sierra nameplate distinguished GMC's truck lineup from Chevrolet's C/K series, targeting buyers who valued GMC's slightly more upscale positioning and robust build quality. This generation featured improved aerodynamics over earlier square-bodies, enhanced interior appointments, and the proven small-block Chevrolet 350 V8 that had become the backbone of GM's truck powertrain strategy. What makes the 1987 Sierra Classic particularly significant is its position as the swan song of the square-body era, before GM transitioned to the more rounded GMT400 platform in 1988. These trucks competed directly with Ford's F-150 and Dodge's D-150, but distinguished themselves through superior ride quality and refined V8 powertrains. The 4x4 variants like this example offered genuine off-road capability with their robust transfer cases and solid axles front and rear. Today, these final-year square-bodies are increasingly sought after by collectors who appreciate their honest, functional design and the ease with which they accept modern performance modifications while retaining their classic proportions and character.
