The primary service that a salvage yard offers is the sale of inexpensive used vehicle parts that have been taken from wrecked vehicles. Furthermore, salvage yards often purchase totaled vehicles and may be able to ship parts all over the country.
A salvage yard goes through wrecked vehicles and finds the parts of the vehicle that may still be in working condition. If a part of a vehicle can still be used, the salvage yard may clean it off and fix it to the point where it can be sold as a spare or replacement part. Salvage yards are also beneficial for individuals who have a wrecked vehicle, as the yard will sometimes purchase the vehicle and help take it off the owner's hands.
