In 1979, the price of a GMC truck varied depending on the model and options chosen, but the average cost for a new GMC pickup truck ranged from approximately $5,000 to $8,000. For example, a GMC Sierra 1500 could be found in the lower end of that range, while more fully equipped models would be closer to the upper end. Adjusted for inflation, this would be equivalent to roughly $20,000 to $30,000 today.
