12. 1971-1980 International Harvester Scout II
In 1971, International Harvester followed up on the success of the Scout 800 series with the Scout II. These days, the Scout II is one of the most valuable and sought out collector trucks. Why? Its performance was plain awesome. The Scout II received a number of cosmetic changes compared to the Scout 1 and was lowered 3 inches closer to the ground. The Scout II offered a variety of engines, from 4 to 8 cylinders, as well as two diesel engines. The 345 V-8 pumped out nearly 200 horsepower and just over 300 lb-ft of torque.
