A dealer must inform a consumer of which of the following regarding repair costs?

A dealer is required to inform a consumer that final repair costs may vary depending on parts. This is essential because the actual costs of repairs can fluctuate based on various factors such as the availability of parts, unexpected complications during repairs, or changes in repair requirements. By communicating this information, the dealer ensures transparency and sets realistic expectations for the consumer regarding the potential changes in price, which can help avoid misunderstandings or disputes later on.

In contrast, options that suggest minimum costs or that repairs must be completed within a certain timeframe do not encompass the variability inherent in repair work. Additionally, claiming that final costs will not exceed the estimate might not always be true, as unanticipated needs can arise. By focusing on the potential variability of costs, this answer reflects the reality of repair scenarios and underscores the importance of clear communication between the dealer and the consumer.
