Car Rental Tips: Remember Before Collecting Your Car from Car Rental Check that the specification is the same as what you booked before signing. Make sure the car is as described and anything extra you requested is included. Have your booking confirmation documents on hand to verify your statements. Once you have the car, check it carefully for any damage so you don't get charged for scratches or dents that you did not cause. Make sure the sales person makes a note of any damage you point out if it has not already been listed. You should be given a copy of the document indicating the pre-existing damage for your own records.
