Car Rental in Vartiosaari, Helsinki, Finland

Some rental agencies might offer a free tank of fuel with your rental. Be aware of the conditions, such as how much fuel to return with to avoid extra charges.

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

When renting a car, especially after travelling by train, allocate extra time for pickup to account for possible delays. Most rental companies offer a 30-60 minute grace period. Sharing your train number can be helpful, but if you're running late, be sure to contact the rental provider to let them know.

Utilize GPS devices or navigation apps for easier routing. This can help prevent getting lost and contribute to a smoother travel experience.

Before returning the car, clarify the return procedures with the rental agency. Knowing where to drop off the vehicle and any necessary inspections can ease the process.

If someone else will drive, confirm the rental company's policy on additional drivers and any fees that may apply. Some might offer complimentary drivers under certain conditions.

Familiarize yourself with the fuel policy. A 'Full-to-Full' policy requires returning the vehicle with a full tank, while 'Same-to-Same' requires it to be returned at the same fuel level. Full-to-Full is generally more economical.

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.
