Zipcar

Have you heard of Zipcars? We've seen a couple around, and I think it's a fabulous idea. There's an application fee and an annual fee, but no monthly fees. Whenever you need a car, you reserve one and then rates start at $6-7 per hour. That includes gas and insurance! So far they're only available in big cities, but if I lived close enough to one I would love to ditch my old car (and all of the money that goes into it).
