Between 1920 and 1930 designers closed the body of the car. While designing a car interior, the value and semantic meaning could be manipulated by opening or closing the space. Simply changing the way the space is divided changed the emotional expression of the space for the consumer (Jaafarnia 2007). The new closed body accentuated by curved glass and privacy had intrinsic value for the consumer.
