What must a dealer do when displaying models with features no longer available from the manufacturer?

The correct approach when displaying models that feature items no longer available from the manufacturer is to inform the buyer about those unavailable features. This obligation is crucial as it maintains transparency and builds trust with potential buyers. When a dealer displays a model that contains features that cannot be provided, failing to inform customers can lead to misunderstandings and dissatisfaction.

By clearly communicating the limitations of what is available, the dealer ensures that the buyer can make an informed decision. This practice not only complies with ethical selling standards but also aligns with legal requirements in many jurisdictions, which emphasize the importance of full disclosure in sales.

In contrast, while the other choices might suggest different actions, they either do not prioritize customer awareness or imply a degree of misrepresentation that could harm the dealer's reputation. Maintaining honesty in sales interactions, particularly concerning product availability, is fundamental to fostering good customer relationships.
