Which types of records must a used car dealership keep?

Maintaining accurate records is crucial for a used car dealership in order to comply with legal requirements and ensure smooth business operations. The types of records defined in the correct option are particularly important as they directly relate to the transactions and ownership of the vehicles sold. Reports of sale, contracts, and titles document the sale of a vehicle, provide proof of ownership, and establish the legalities involved in the sale process. These records help in tracking sales history, handling any disputes that may arise, and ensuring transparency for both the dealership and the customer.

While other types of records, such as employee evaluations, advertising materials, and operational documents, are valuable for running the business, they do not hold the same legal significance regarding vehicle ownership and transaction validity as the records specified in the correct answer. Hence, the necessity for reports of sale, contracts, and titles stands out as a top priority in a used car dealership's record-keeping practices.
