it is because they are a malluable, waterproof, good conductor of heat metal.
The ferrous metal commonly used to make car bodies is steel. Steel is chosen for its strength, durability, and formability, making it ideal for providing structure and protection in automotive applications.

Car bodies are primarily made of steel due to its strength, durability, and ability to absorb impact energy, which enhances passenger safety in collisions. Steel is also relatively cost-effective and can be easily molded into complex shapes for design flexibility. Additionally, it provides good corrosion resistance when treated, contributing to the longevity of the vehicle. Finally, steel is recyclable, making it a more environmentally friendly choice in automotive manufacturing.
