Zip-car is a car-sharing sort of thing, where there are different membership levels, depending on frequency of use.
I have the $50.- per year membership, for occasional use (the vet). Then there is an hourly use charge that depend on the car and time of the week.
I usually get a car that's $10.- per hour during the week ($12.- Friday - Sunday). The fees include everything, even gas.
The cars are kept in a neighborhood garage. Once the car is reserved over the internet, I can just pick it up by swiping my card over a sensor on the wind shield. The doors open and the keys are inside. When the gas goes below 1/4 full I use a credit card that stays in the car to fill it up before I drop off the car.
Of course, switching to my current vet has brought my vet expenses so much, that the Zip-car is practically free.
