What best defines a used motor vehicle dealer?

A used motor vehicle dealer is best defined as someone who negotiates the sale of a used motor vehicle with the intent to profit. This definition captures the essence of what it means to be a dealer in the used vehicle market. Such individuals or businesses are primarily focused on the resale of pre-owned vehicles, which entails acquiring these vehicles, often refurbishing or cleaning them up, and then selling them to consumers or other dealers.

The emphasis on negotiation highlights the active role these dealers play in managing transactions and ensuring profitable sales, which is central to the definition of their business activity. This contrasts with other choices, such as the option that describes a person who sells only new vehicles, which does not pertain to used vehicle dealings at all. The dismantling of vehicles for parts or buying vehicles on behalf of dealerships reflects activities that are not specific to the traditional role of a used motor vehicle dealer, as they do not involve direct sales to consumers for profit.
