Rental cars refer to vehicles that are available for rent from a company or agency. These companies offer various types and sizes of vehicles, ranging from economy cars to luxury sedans, SUVs, minivans, and even trucks. The renter pays a daily or weekly rate to use the vehicle for a specified period of time, usually between 24 hours to several days. Rental cars are often used by individuals who need a temporary replacement car while their own is being repaired or serviced, or for those who need a vehicle during travel but do not want to bring their own. They can also be utilized by businesses that require vehicles for employees or clients, or for special events and occasions.
