Of what good use is an old scrap car in your garage? If your car is not fit to be on the roads anymore, consider selling it off to scrap car dealers. Several of the old car parts can be recycled and made into usable products. The car doors, bonnet, boot, upholstery, mirrors, windshield, engine, battery and many other parts of the car can be recycled individually. The car is taken apart piece by piece and then recycled.
