The year 1978 saw the advent of a vehicle that would become a symbol of rugged capability and enduring reliability: the GMC K25. This full-size pickup truck, manufactured by General Motors' truck division, was designed to handle the toughest of tasks with grace and power. As a member of the celebrated C/K series, the K25 was GMC's answer to the demands of heavy-duty work and off-road challenges. A unique fact that car enthusiasts might find fascinating is that the K25 was among the first trucks to offer a combination of four-wheel drive and an automatic transmission, making it a pioneer in its class.
