When you book a vehicle with Sixt, you can also choose from a range of extra services to tailor your car hire package to your needs. For example, if you'd like some help in getting around, we can provide a Sat Nav system. There's an unlimited mileage option, which is great if you plan on driving a long distance. Or, for families with small children, we have child seats too. Simply choose your extras whilst making your booking. Please be aware that we do not guarantee a specific model of vehicle, but one in your chosen rental category.
