Cheap National Car Rental Deals at Gare Montparnasse, Paris

Many rental companies require payment by credit card and may not accept debit cards. If you only have a debit card, check the rental company's payment policies in advance and look for suitable options.

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.

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

Be aware that some rental companies impose age restrictions or additional fees for drivers under 25. Make sure to check the company’s age policy when booking.

Before traveling, familiarize yourself with local driving laws and regulations. This can help you avoid fines and ensure a safe driving experience.

Ask about potential extra costs, such as fees for insurance or airport charges, to plan your budget wisely.

To save on refueling costs when departing from Gare Montparnasse, look for deals with a 'full to full' tank fuel policy, or even better, a free tank fuel policy, as opposed to a 'half-full to full' one.

Pick a time that aligns with your flight arrival to avoid any complications from delays.
