If zipcar's like our Enterprise Car Club here in Nottingham, the massive advantages are: 1. No need to travel to rental (out-of-town) centres, it's round the corner 2. Don't have to pick-up or drop-off during office hours 3. Don't have to wait half-hour for all the paper-work and stuff 4. Don't have to answer a bunch of obnoxious questions 5. Don't have to dig out a load of documentation 6. Can decide to take one on a whim, with no notice 7. Can hire it for 2 or 3 hours instead of days You pick up the car and go. I don't use it much as generally taxis are cheaper, but if I want to go on a country walk or do a large shop, it's very handy. I think it works out slightly more expensive if you hire it for whole days, but again all those conveniences apply.
