What were the cars in 1960s made out of?

Cars in the 1960s were primarily made of steel, both for the body and the chassis. However, other materials were also used, though to a lesser extent:

* Steel: This was the dominant material, forming the body panels, frame (in body-on-frame constructions), and many internal components.

* Aluminum: Started to see increased, though still limited, use in some components like engine parts (cylinder heads, etc.) to reduce weight. It wasn't common for body panels yet.

* Glass: Used for windshields, windows, and headlights.

* Rubber: Used for tires, seals, hoses, and various other parts.

* Plastics: Began to appear more frequently in interior components like dashboards, trim, and some exterior parts, though often in conjunction with other materials. These early plastics were often less durable than modern plastics.

* Chrome: Plating was used extensively for decorative trim, bumpers, and various other exterior details.

* Fabric/Vinyl: Used for upholstery, carpets, and headliners.

It's important to remember that the 1960s represented a transition period. While steel was king, the use of aluminum and plastics was steadily increasing, laying the groundwork for their more prominent roles in later decades.
