A fleet is a group of vehicles, often focused on a single discipline, that are owned and managed by a single company, non-profit organization, or government organization. A fleet vehicle is a car owned by an organization, not an individual. Businesses, non-profit groups, and government agencies have a fleet of vehicles available for specific purposes and are regularly maintained by professionals. When a vehicle reaches a certain age or mileage, it is replaced.
If you're looking for a used car, expanding your search to include fleet vehicles can help you get an offer. If you're willing to pay more for maintenance in exchange for a lower car payment or you can buy a car without a loan, fleet vehicles may be a good option.
