As a security measure, we add a temporary authorization of up to $150—usually for first-time renters only. This isn't a deposit and we do not actually collect any of these funds. We temporarily authorize your card to ensure there are sufficient funds in the case of an extension or community violation such as a smoking fee or a fuel fee.
The authorization is voided and the money is not taken from your card. However, this will usually show as a pending charge for 3-5 business days before it disappears. When the charge settles you will only see the actual cost of your trip.
