Avis AVIS is the leading car rental company in Europe, Africa, the Middle East and Asia, serving more than six million customers a year through a network of over 2,500 locations in 110 countries. The essence of our success has been a singular vision of building the best and fastest growing company with the highest profit margins in the business of car rental though continuous investment in our network, our technology and most of all, our people. This coupled with the "We try harder" positioning delivered so distinctively by Avis employees throughout the Avis system, has taken us from a three-car operation at a single airport in Detroit to a global service company.
