Scrap cars may look useless, but they hold more value than you might think. After undergoing the crushing process, the hulk may be given to a scrap processor for reuse. The components are also given to auto body shops for resale.
Your car might not be useful to you anymore, but whatever it holds may prove vital for someone else. The environment will also become healthier when there are fewer vehicles left sitting around and wasting away. Scrap cars are beneficial to everyone!
