Rent a car in Italy by contacting or walking into a car rental agency and reserving a vehicle. When you pick up the car, the agency typically requires you to sign a contract that delineates the make and model of the vehicle, initial mileage record, and term for the rental. The contract also includes a compulsory collision damage waiver and theft protection clause as mandated by Italian law.
Most larger Italian cities feature offices and lots for international car rental companies such as Avis, Budget and Hertz. Checking with online car rental price aggregation sites such as RentalCars.com, Vayama.com and Mobissimo.com sometimes yields special deals. Likewise, price consolidation sites such as AutoEurope.com and Carrentals.com sometimes offer cheaper vehicle rental prices than those available from the major companies.
One way to save time and money is to only rent a car for days specifically spent outside of the major cities. Many Italian metropolitan areas have Zones of Limited Traffic in the city center, forbidding or charging fees for automobile operation within the area. Additionally, parking is typically expensive and hard to find. Cheaper and more plentiful mass transit options such as the train, bus or subway effectively reach most portions of the cities.
