A while ago, when you would be in need of scrapping your car out of either aging or development of a certain failure, you would be required to pay to have the vehicle disposed.  Alternatively, you were to look for a scrap yard and bid the car goodbye as you arrange for a lift back home with a handful of change.
The process of scrapping your car has however changed resulting from the development of the internet and a number of shifts in legislation therefore giving you a plenty of options on how to deal with your unwanted car.
One such option is by using an online scrap valuation like CarTakeBack.com. you provide your registration number, postcode and the site fetches you the best local prices. The quotes to expect depends on size of the car, the location and the scrap metal prices.
The other alternative of scrapping your car is by donating it to charity through some organizations such as CharityCar.co.uk or GiveACar.co.uk.  These organisations pick your car for free, sell it or scraps it then gives the proceeds to the charity of your choice.
