A Car Rental company is a company that rents cars and other vehicles for a short period of time generally ranging from a few hours to a few weeks. It is basically a rental shop often organised with a number of outlets located in exceptionally busy locations such as airports, and city areas. The majority of rentals come from people who actually own their own car that is temporarily out of reach or in for repair. Because of the variety of sizes of their vehicles some car rental companies may also serve the self moving industry needs by supplying trucks and vans. Car rental companies operate by buying or leasing a certain amount of vehicles and then renting them to their customers for a fee. These companies can be structured in several ways, they can be owned outright or they can be leased, or even under a buy back structure arranged with the manufacturer. Usually, at the end of the vehicles life, rental companies will sell them on to the used market.
