There is no better way to see Italy than by car
Italy! 50 millions of tourists every year! Most of them are those who prefers to feel like home in any country. It means to go wherever and whenever changing the program as you wish. All you need for that is car rented for your journey.
Whichever way - by air, water or land - you are going to Italy, you will almost certainly find yourself in a city where Avis has a rental station.
