ZipCar is a membership-based car-sharing company that lets you rent cars by the hour (gas + insurance included) in many metro areas and college campuses. It can be good deal for those thinking about having one less car in your household (or who don’t have a car but occasionally want one). Right now, you can get $25 in free driving credit when you join. You’ll need a driver’s license and credit card. Plan prices vary by location.
If you don’t drive your car very much, adding up the total cost of depreciation + car insurance + maintenance + parking + gas can actually make ZipCar a much cheaper alternative (ZipCar savings calculator). Also, we were selling an old bookshelf on Craiglist once and the buyer rented a Honda Odyssey via Zipcar to pick it up.
