An aftermarket part is any part for a vehicle that is not sourced from the car's maker. If the parts are direct replacement parts, they will not void your car's warranty. A number of companies make parts designed to function the same, or in some cases even better than the original.

The sale of reusable salvage from old cars is only a small piece of the auto recycling pie. Once cars are crushed, they're shipped off to a recycling center where they are shredded and separated into small pieces, which are then sorted into various metals.
