Zipcar owns the car, and decides the base level for the car. They keep the cars in good shape and had relatively strict rules on what you can do. Most cars on the road are in worse shape than most rental cars. If I have a beat up clunker, with windshield damage, can I rent it out? If so, does each person who rents it need to itemize all of the damage when they pick up the car? I fixed the windshield, but the next person to rent it followed another car too closely on a gravel road and knocked a chip out of the windshield again. Do I take the person to court to resolve the issue, or do I work through the rental agency? ZipCar prohibits smoking, and pets must be in carriers. But I smoke, and let my dogs on the back seat. (Okay, no I don't - this is hypothetical.) Can I still rent out the car? If so, do I need to indicate "may stink of smoke" and "not for those with dog allergies"? Oh, and my father-in-law borrowed the car and smoked while in it. Do I need to change the setting for a few weeks to "it smells like cigarette smoke, but that doesn't mean you can smoke"? It's much more complicated when there's no central authority who can require a core set of rules.
