Numerous benefits are gained when consumers buy used parts. Recycling auto and truck parts saves the natural resources and energy, i.e. manufacturing steel, used to produce new parts. Costs are reduced when insurance companies choose used parts for repairs. Insurance companies save once on the price of the part, and again when fewer total vehicles are paid out. But, perhaps the biggest advantage to buying used parts, at least the one you can instantly see, is the price of used parts compared to new.
