* Plastics: This is by far the most common material, used for dashboards, door panels, consoles, and many other parts. Different types of plastics are used, ranging from hard and brittle to soft and flexible, often with different textures and finishes to mimic other materials.
* Fabrics: Used for seats, headliners, and sometimes door panels. These can range from inexpensive woven polyester to more luxurious materials like leather, suede, or microfiber.
* Metals: Used for various trim pieces, seat frames, steering wheel supports, and other structural elements. Common metals include steel and aluminum.
* Leather (or Leatherette): A more premium material often found in higher-end vehicles, used for seating and sometimes other interior components. Leatherette is a synthetic material designed to mimic the look and feel of leather.
* Rubber and Elastomers: Used for seals, gaskets, and other components that require flexibility and durability.
* Foams: Used for padding in seats, armrests, and other areas to provide comfort and support.
* Glass: Used for windows and sometimes other smaller interior components.
The specific combination and quality of these materials vary greatly depending on the price and features of the vehicle.
