It's okay if you drive more kilometres in a month than what is set out in the agreement. It is important that the total mileage of the car at the end of the agreement does not exceed the agreement mileage. If you cancel your subscription before the end of the agreement, the mileage allowance will be calculated by multiplying the monthly mileage by the full number of months the car has been used. The standard monthly mileage is 1,000 km, or 12,000 km per year. Monthly mileage can be increased for an additional fee. This should be agreed on with the SIXT+ representative before the agreement is signed.
