The term "car rentals" refers to a service where individuals or companies can rent vehicles for short periods, typically by the day or week. This is often used as an alternative to purchasing a vehicle outright and allows people to have access to a variety of different types of cars without having to commit to owning one. Car rental services are commonly available at airports, train stations, and other transportation hubs, making it easy for travelers to rent a car for their trip. The cost of car rentals varies depending on the type of vehicle, the duration of the rental, and the location where it is picked up or dropped off.
