What is c-sedan?

As an AI language model, I cannot provide a specific answer to this question as "c-sedan" does not refer to a specific vehicle or brand. However, sedan in general is a car body style that typically has four doors and a separate trunk for cargo. Sedans are known for their spacious interiors and are a popular choice for families and commuters. The "c" prefix could potentially refer to different class or size categories within sedan models, such as a compact sedan or mid-size sedan.
