It pays to check prices before you begin. Look into the current leasing rates with an aggregator, a meta-search engine that checks rates at retailers, booking sites and travel agencies. Some aggregators include Kayak.com, Momondo.com and Breezenet.com. After you have the lowest quote, you are ready to contact leasing companies directly.
Check for better prices with reputable companies. Carrentals.com is a newer car consolidator that offers rentals worldwide, including the U.S., Asia and Europe. Easycar.com, known for EasyJet also rents cars. They also provide rentals for the fuel-efficient SmartCars and inexpensive convertibles. AutoEurope.com provides both short and long-term leases and can show you if renting or leasing is cheaper in the long run. Also try Renault Eurodrive at renaultusa.com. This is a direct line to the company's leasing program.
After booking your lease, you will need an international driver's permit. Stop by your local AAA and for a fee of about $15 for photo processing and paperwork, you can get your permit. You can also get guide books and they can set you up with information about fuel costs in Italy (gas is about $6.60) and directions to any points of interest you plan to visit.
