HOURCAR is a car-sharing organizations that gives you access to a fleet of earth-friendly cars whenever you need them.  

HOURCAR buys, insures, and maintains a fleet of member-shared cars. HOURCAR takes on all the responsibilities of owning the vehicles, including paying for fuel. HOURCARs are parked in hubs near members’ homes and workplaces. Members make HOURCAR reservations online or by phone, and pay monthly dues and car usage fees. You pay only for what you use!

Research shows that many car owners use their vehicles only a few hours a day. Why not eliminate an underused car and begin car-sharing? Car-sharing spreads the fixed costs of car ownership among several people. You still have access to a car when you need it, but you don't pay for it around the clock!
