GMC (an initialization that originally stood for “Grabowsky Motor Company” but now represents the “General Motors Truck Company”) began in Detroit in 1900 and has been manufacturing durable, heavy-duty pickup trucks since 1911. As part of General Motors, the brand’s consumer-oriented trucks often shared parts and similarities with Chevrolet pickups, and were popular with buyers who appreciated a reliable workhorse. While GMC was focused on the commercial market early on, it began selling personal use trucks in the 1930s, with more creature comforts. Following a pause for wartime production in the 1940s, GMC introduced its New Design pickups in 1947 and its Blue Chip range in 1955. The GMC Sierra line of pickups debuted in the 1960s and have continued for decades since. Collectors today buy GMCs for many of the same reasons buyers always have: the trucks’ hard-working “professional grade” reputation, their rugged utility, and their strong performance with towing or hauling just about anything one could want.
