Glad to see this…(I have been asking for about three years..)

Finally, Zipcar is in Richmond

Zipcar is known for renting cars, usually the environmentally friendly type, by the hour in cities and college campuses across the country. Before coming to Richmond, Zipcar already had cars at the University of Virginia, Old Dominion University and The College of William & Mary.
That’s why it was hard to discern why the company continued to bypass Richmond. BizSense has an inquiry in to Zipcar’s corporate headquarters to find out why Richmond finally got its chance.

VCU offers Zipcars, additional bus service

The cars are not limited to student use, though clean driving records are required. VCU students must be 18 years old and community members at least 21 to rent a car at a cost of $8 an hour on weekdays and $9 on weekends. That includes gas, insurance and 180 free miles.

There’s also an annual membership fee of $35 for students, faculty and staff. Drivers not affiliated with VCU pay a $50 annual fee plus a $25 application fee.
