CONSIDER FOR A SECOND... You register online. You receive a membership card via mail. You reserve a car. You hold the membership card against the windshield to unlock your car. You drive away. You return the car when you are done. Beginning January 18th, two self-service, fuel efficient Zipcars will be available for use 24 hours a day, seven days a week. The cars are located in reserved spaces in the Clark University Parking Garage on Downing Street and they are available to all staff and students ages 18 and older. Gas, insurance, 180 free miles, reserved parking and roadside assistance are included in low hourly and daily rates. Faculty, staff, and students will be able to join Zipcar for $35 and can drive for as little as $8 per hour or $66 per day weekdays and $9 per hour or $72 per day on weekends. Students also get $35 in free driving credit as part of a launch promotion. All members 21 and over will have access to Zipcar's network of more than 6,500 vehicles throughout the UK and North America.
