You will have the ability to pay online prior to the start of the trip or after you see the car in person. The full price including the security deposit MUST be paid before you receive the keys. If you incur additional fees such as mileage overages, parking tickets, cleaning fees, etc. you will be charged after the trip ends. We will deduct from the security deposit prior to charging the card on file, so please make sure that you have the proper funds available in case we need to charge the card.
