Zipcar has been such a huge blessing to us here in NYC! The price includes insurance and gas. They have a gas card right in there. We've consistently found them cheaper than rentals and so much more convenient. You just hop online, find the car you'd like for as little as half an hour at a time, and away you go. They're all over the US now and also in Toronto and London. Click the button below and we'll both get a $25 driving credit!
