Operating across 470 cities and towns and 400 college campuses—plus more than 50 airports—throughout the United States, Canada, Austria, France, the United Kingdom, and Turkey, Zipcar helps green the environment and cuts out the costs of vehicle ownership with its four-step process that lets members reserve vehicles on the fly. Members can pull up the website or use the Zipcar app to choose from hundreds of cars locally in more than 30 makes and models, including BMWs, cargo vans, sedans, and eco-friendly hybrids. At the time of pick-up, members simply hold their Zipcar card up to the parked vehicle's windshield, wait for the welcoming click of unlocking doors, and drive off to realize the dream of using a drive-thru. Reservations—by the hour or by the day—also include insurance and gas. Zipcar's team also touts the eco-friendly benefits of their business: by lessening the number of cars on the road, the company hopes to lower pollution, dependence on oil, and the need to chop pine trees into air fresheners.
