LEWISTON – An hourly car rental is becoming an overnight success.

Bates College is the first Maine location for Zipcar, a car-sharing company that offers self-service on-demand cars by the hour or day. Starting this week, it’s offering a pair of Toyota Prius automobiles for $7 an hour.

Assistant Dean of Students Keith Tannenbaum predicts the cars will ease parking problems and cut down on pollution, in addition to helping students get around.

Students, faculty or community members can become a member for $35, reserve a car online and use their magnetized membership card to unlock the vehicle. Gas, insurance and a prime parking spot on the campus are included.
