Visit or telephone your local travel agent. Provide your dates of travel, cities you will visit, and your car rental and fuel budget. Request information about specials and discounts you can take advantage of. Ask for a car with a GPS system to make it easy to find places you plan to visit.
Visit the car rental section at the airport. Check with agencies that have a global presence such as Hertz, Enterprise, Alamo and Dollar. Insure that the price the clerk at the counter quotes you is "turnkey" so that you are aware of the total cost (including the tax). Ask if you can waive the payment for collision damage. Keep in mind that some rental agencies may require you to pay for this insurance, especially if you are not a resident of Italy. Ask about drop off charges if you want to pick up and drop your car off in different locations. Check with the clerk about re-fuel policies. Make sure you are aware of typical cost of "Gasolio," or gasoline, so you can properly budget for fuel. Present your local driver's license or international driver's permit and passport. Keep in mind that many car rental agencies in Italy require that you pay for your car with a credit card.
