In the United States, renting a car is a fairly common practice that businessmen, families on vacation, and foreign visitors engage in. Car rental agencies (such as Herz, Budget, Enterprise and many more) have branch offices in nearly every city in America, although they are most commonly found at airports. There are also brokerage companies such as Rentalcars.com, Economy Bookings, usacarsrental.com CarRentals.com, Travelauto and AutoEurope.com who exclusively deal with car rentals. A wide variety of car makes and models are available to rent -- everything from a 4X4 pickup truck or full size SUV to a tiny VW Beetle. Prices typically vary depending on the make and model (a high-end sedan or sports car will be very expensive, whereas a small economy car will be much less, for example) and charges per day can vary -- anywhere from $15 to $85 or more. Reservations should be made in advance, usually without the need for a credit card, although you may be able pop into a rental office and secure a car without a reservation, depending on the time of year. Hybrid cars are available and popular, so if this is your aim, you may want to make a reservation, and you should expect to pay more than for a typical compact car.
