Aside from weighing up all the best packages online before booking, there are plenty of other ways you can cut the cost of your Sixt car rental premium. Try:

• Adding just a single named driver to the policy;
• Collecting the car away from the airport;
• Booking your vehicle long before packing your vacation bags.

You will need to be at least 21 years young to be able to bag yourself a Sixt rental car. It's also normal for people under 25 to pay surcharges that are calculated per driver, per day.

Looking to share the pedal pushing and steering? That shouldn't be a problem. Most Sixt cars will make it easy to add a second driver to the mix, though it might increase the cost a little.

Unlimited mileage is the best option for travelers who don't want to keep an eye on how far they've driven. It basically means you can do whatever distances you like without incurring extra costs. Just be sure to check there aren't any extra restrictions on where you can venture to.

There's sometimes a mix of different fuel policies to pick from. However, the vast majority of vehicle hires with Sixt will be full-to-full. That does exactly what the name implies – you pick up the car with 100% gas and return it with 100% gas.

With big-booted estates and oversized SUVs, look-at-me convertibles and luxury business rides, the Sixt car rental fleet has to be one of the most eclectic on the globe. That's especially true in popular destinations, where the full range of cars is usually on offer, so long as you book nice and early to secure yours.

All car renters will need to present their driver's license and a credit card when they come to pick up their wheels at the Sixt counter. On top of that, insurance is a must. You might already have it thanks to existing car or card policies. If not, it's a cinch to add to bookings over CarRentals.com.

Large car, small car, or convertible, the choices are often endless when you have the Sixt fleet at hand.
