Zipcar: Car Sharing

Meanwhile car sharing initiatives can be found all over Europe, not so many are present in the US. But if it happens that you visit Boston, New York, Washington DC or Denver, you can use the services of Zipcar. The company rents cars that have parking lots spread through the city applying rates according to hours using the service.
Convenience of the system is twofold: flexibility of use (private transportation when needed) and attractive localization system. When visiting the site, availability and location of cars is shown using Google Maps.
