compare to rental
You could rent a car (but that would be silly).
Car rental is great if you don't mind standing in long lines. Not to mention, you're usually paying for gas, insurance and parking. But that's not what the Zipcar way of life is all about. With Zipcar, you're free from paying for all three (they're included) and your Zipcard opens the door to any Zipcar in any Zipcar city – whether you're there for business or pleasure.
