Car Hire in Hermanni, Helsinki, Finland

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.

Some rentals have mileage limits, while others provide unlimited options. Read the policies carefully to avoid unexpected charges upon return.

If sharing driving responsibilities, check the policies regarding additional drivers. Some companies charge fees for each extra driver, while others may include it for free under certain conditions.

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 rental companies prefer credit cards and might have limitations on debit card usage. Always check the accepted payment methods prior to booking.

Some rental companies offer a free tank of fuel with your rental. Be sure to understand the terms, including how much fuel you need to return the car with and any potential fees for not meeting these conditions.

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.

Research toll roads on your travel route and familiarize yourself with their payment methods. Some rental agencies offer toll transponders for convenience.
