Car Hire in Tongsŏn-dong, Seoul, South Korea

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.

Be sure to know if your rental includes roadside assistance. This can be crucial in the event of breakdowns or emergencies during your rental period.

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.

Before booking, review the rental agreement for any hidden fees such as airport surcharges, additional driver fees, or late return penalties. Understanding these can help you budget more effectively.

Before driving away, examine the rental car's interior for cleanliness and any functional issues. Ensure features like the radio and air conditioning are working properly.

When booking, check if the rental company offers extras such as GPS or child seats. These can enhance your driving experience but may incur additional costs, so it's wise to factor them into your budget.

Be aware that some rental companies have age restrictions or may impose additional fees for drivers under 25. Always verify the age policy before booking.

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.
