Book Cheap Hertz Car Hire Deals in Bonfim, Porto, Portugal

Before you book, review the rental agreement for any hidden fees, such as airport surcharges, additional driver costs, or penalties for late returns. Awareness helps in budgeting appropriately.

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.

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.

Some rental agreements come with mileage limits, while others offer unlimited mileage. Make sure to review the mileage policy to avoid unexpected fees.

Many rental firms prefer credit cards and may not accept debit cards for payment. If you're using a debit card, confirm the company's policies before making a reservation.

Ensure your rental agreement, ID, and insurance details are easily accessible throughout your rental period for quick access if needed.

Before renting a car, check if your personal car insurance covers rental losses. Many personal auto insurance policies and credit cards offer coverage for rentals, which could save you from extra insurance fees.

Most car rental companies will ask for a credit card deposit, which is usually held temporarily. Inquire about the specific deposit amount and the process for releasing it once the rental is complete.
