Give me some credit. I know that. I am trying to understand why a different car is required for the trip home. Can you just leave the C2G vehicles wherever and whenever you are done with them or do you have to bring them to designated pick-up/drop-off sites? And, yes, I am confusing some of the details with C2G with ZipCar and it does look like C2G have figured out some things (like fractional hour pricing).
