so they can get struck by lightning! heheh

no its so you have something to slit your wrists on when the engine blows up cause the guy at jiffy lube forgot the drain plug......im kidding cars are actually made out of metal and sevral types of plastics, rubbers,fabrics, natural and other synthetic materials its a balance of cost of materials versus expected lifespan also taking into account the purpose of the part and several other aspects of design and functionality. but basically cars are made mostly of metal (iron,steel, aluminum,) because its durable and relativley cheap when you consider the other option carbon fiber is on alot of high end cars and its extremely durable and extremely light but it costs alot of money to manufacture
