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’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.

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

If you have a specific vehicle model in mind, consider rentals that guarantee the car type you want. This avoids surprises at pickup when you receive an alternative vehicle.

Most rental companies will require a credit card for the deposit, which is typically frozen in your account. Make sure to inquire about the specific deposit amount and the policy for releasing the freeze.

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

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