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.

If you're looking for more comfort or features, inquire about upgrade options at the rental desk. Sometimes, upgrades are offered at a discounted rate at pickup.

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.

Before your trip, confirm if your rental includes roadside assistance. This can be crucial in case of breakdowns or emergencies during your rental period.

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.

Inspect the vehicle for pre-existing damage and take photos to ensure clarity later.
