Car Hire in Chŏngnŭngil-tong, Seoul, South Korea

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

If you have a specific vehicle in mind, opt for rentals that guarantee your chosen car type. This ensures that you receive the vehicle you expect, rather than being offered an alternative.

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.

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.

If you're traveling with pets, confirm the rental company's pet policy before booking. Some companies allow pets but may have specific fees or restrictions, so it’s best to clarify in advance.

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

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.

When renting a car, especially after travelling by train, allocate extra time for pickup to account for possible delays. Most car hire 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 car hire provider to let them know.
