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.

If you plan to share driving, check if the rental company allows a second driver and whether there are additional fees. Some companies offer free second driver options under certain conditions.

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.

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.

If you plan to drive off-road, confirm with the rental agency whether it's permitted. Not all vehicles are suited for off-road conditions.

If you’re sharing driving duties, check the policies on additional drivers. Some companies charge extra fees, while others may allow it for free under certain conditions.

When selecting insurance, consider if it includes free excess coverage. This means you won’t have to pay a deductible in the event of damage, adding an extra layer of security.

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.
