If your car is in a roadworthy condition, you may be able to sell it privately or trade-in when you buy a new one.
Bring them to an authorised facility
An end-of-life vehicle is a specified vehicle, such as a car, which is discarded or is to be discarded by its registered owner as waste. Vehicles normally reach the end of their useful lives, either due to age (typically around 12-14 years), or because of heavy damage following an accident. There is no fixed age, therefore, at which a vehicle can be considered an end-of-life vehicle. An end-of-life vehicle must be deposited at an authorised treatment facility. Each vehicle manufacturer or importer is required to have a national collection system in place made up of at least one such treatment facility in every city and council area. These facilities provide a free take-back service for vehicles of that producer’s brand. There may also be an independent facility in your area that will accept your end-of-life vehicle. If an end-of-life vehicle is deposited at an unauthorised facility, the owner will not receive a certificate of destruction and may remain recorded as registered owner of the vehicle on the Department of Transport, Tourism and Sport National Vehicle File.
