Book Cheap Sixt Car Hire Deals in San Francisco, Madrid, Spain

Some rentals have mileage limits, while others provide unlimited mileage. Review these policies carefully to avoid unexpected charges.

Research fuel prices in the area where you'll return the vehicle. Filling up at a local station may be cheaper than paying for fuel through the rental company, especially if they charge higher rates.

If you're looking for extra comfort or features, ask about upgrade options at the rental counter. Often, discounted upgrades are available at pickup.

Before departing, check the interior of the rental car for cleanliness and any functional issues. Ensure equipment like the radio and air conditioning works properly.

When renting a car, understand the fuel policy. A 'Full-to-Full' policy means you return the car with a full tank, while 'Same-to-Same' means you return it with the same level of fuel. Full-to-Full is often more cost-effective.

When hiring a car in San Francisco, Madrid, be aware that rentals are charged per day. For instance, Sixt charges per day, so if you rent for more than 24 hours, you’ll incur an additional day’s charge. Plan your hire period to avoid extra costs

Before leaving the rental location, inspect the car for any existing damage and ensure it’s documented. Take photos if necessary to avoid disputes when returning the vehicle.

Be aware that some rental companies impose age restrictions or additional fees for drivers under 25. Make sure to check the company’s age policy when booking.
