Which aspect does NOT define a motor vehicle dealer?

The correct response highlights that a motor vehicle dealer is typically engaged in transactions involving sales to consumers or as intermediaries in vehicle transactions. When a dealer sells motor vehicles exclusively to wholesalers, they do not fulfill the broader roles and functions characteristic of a motor vehicle dealer. Dealers are generally recognized for their involvement with the public, such as retail activities, promoting vehicle ownership exchange, and facilitating direct sales to consumers.

In contrast, selling only to wholesalers limits the definition and scope of a motor vehicle dealer's functions. Motor vehicle dealers operate in a retail capacity and are essential to consumer sales, while those selling solely to wholesalers do not engage directly with the end consumer. This distinction is crucial in understanding the various roles within the automotive sales industry.
