Book Cheap National Car Rental Deals in São Domingos de Benfica, Lisbon, Portugal

Prior to booking, check for any current promotional offers or discounts. Many rental agencies provide seasonal deals or early booking discounts.

Look up fuel prices in the area where you'll return the vehicle. Refueling at a local station is often more economical than paying rental company rates.

When booking, check if the rental company offers extras such as GPS or child seats. These can enhance your driving experience but may incur additional costs, so it's wise to factor them into your budget.

Familiarize yourself with the fuel policy for your rental. A 'Full-to-Full' policy means returning the car with a full tank, while 'Same-to-Same' indicates you return it at the same fuel level. Full-to-Full is usually more economical.

Ensure that you have a valid driving licence with at least one year of driving experience. If you are a foreign driver travelling to Lisbon, an international driving permit may be required. Remember, hire rates can be higher for drivers under 25 or over 70

If you have a specific vehicle in mind, opt for rentals that guarantee your chosen car type. This ensures that you receive the vehicle you expect, rather than being offered an alternative.

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.

Some rental companies offer a free tank of fuel with your rental. Be sure to understand the terms, including how much fuel you need to return the car with and any potential fees for not meeting these conditions.
