Which of the following is considered a used vehicle?

A demo vehicle with 1300 miles is considered a used vehicle because it has been driven by individuals other than the original seller, typically for test drives or as a courtesy vehicle. The key factor in determining whether a vehicle is classified as used is whether it has been previously owned or operated, which applies to demo vehicles that have accrued mileage from customer use. In contrast, a new car with less than 100 miles remains unsold and retains its new status since it has not been used by others in a significant way. A vehicle that is older than five years does not automatically categorize it as used; age is not the primary factor used in determining the classification of a vehicle. Finally, a vehicle that has never been sold is still considered new since it has not changed ownership or been utilized by consumers. Thus, the demo vehicle is the clear choice as a used vehicle among the options provided.
