Some companies may provide a complimentary tank of fuel with your rental. Understand the conditions, such as how much fuel you need to return with to avoid fees.

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.

If you plan to have someone else drive, check if the rental company permits a second driver and whether there are extra fees involved. Some may offer free additional drivers under specific conditions.

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.
