Old models of International trucks are found on websites that provide public listings for antique vehicles, such as ClassicCars.com or eBay.com. These listings are populated by dealerships across the United States, so it is a good idea to check the location of the vehicle before considering a purchase.
Old International trucks range from $13,000 to $100,000, depending on the model. As of July 2015, the 1935 International C-1 De Luxe Flower Wagon is priced closer to the high end on OldRide.com, whereas a newer model, such as the 1979 International Scout, is priced at $17,000 in the same listings.
Old International trucks found on eBay.com are priced between $4,000 and $25,000, but there are International trucks at much lower prices that require significant repairs before they are safe to drive. Some vehicle merchants at eBay.com sell parts from International trucks to people looking to repair their own vehicles.
Navistar International Corporation, previously International Harvester Company, stopped selling their old models in 1986 when the company transitioned to large diesel trucks instead of the agriculture-based Harvester models, which were smaller than most current models as of 2015. International Harvester trucks made before 1986 are typically farming vehicles no longer in use.
