Which option reflects what records must be retained by a dealer?

The correct choice reflects the requirement for dealers to retain specific records that are essential for compliance and operational accountability. Transfer records and odometer statements are critical documents that provide important details about vehicle transactions. These records are necessary for verifying the authenticity of sales, monitoring odometer readings for potential fraud, and ensuring that all vehicle transactions adhere to legal regulations.

Having transfer records helps track the chain of ownership of vehicles, which is crucial in case of disputes or inquiries related to the vehicle's history. Odometer statements are vital for preventing odometer fraud and ensuring that consumers receive accurate information about the mileage of a vehicle at the time of sale.

In contrast, retaining sales invoices only does not encompass all the necessary documentation required by the regulation, as the scope of record-keeping is broader. Customer feedback documents, while valuable for customer service and satisfaction insights, are not mandated records for compliance. Advertising materials, though useful for marketing and promotions, do not directly relate to the regulatory requirements that govern vehicle transactions. Thus, the emphasis on retaining transfer records and odometer statements ensures that dealers meet legal obligations while maintaining transparency in their transactions.
