What must a salesperson do when a customer wishes to demonstrate a vehicle?

When a customer wishes to demonstrate a vehicle, the salesperson must accompany the customer. This is important for several reasons. Firstly, accompanying the customer ensures the safety of both the customer and the vehicle. Salespeople can provide real-time information about the vehicle's features and capabilities during the test drive, enhancing the customer’s experience and helping them make an informed decision.

Additionally, being present allows the salesperson to address any questions or concerns the customer might have while driving, fostering a better rapport and building trust. It also helps prevent potential misuse of the vehicle while ensuring compliance with dealership policies regarding test drives.

The other options either lack the necessary support structure for a successful demonstration or fail to comply with dealership practices.
