Car Hire in Sin’gongdŏk-tong, Seoul, South Korea

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.

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.

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.

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.

If you plan to drive off-road, confirm with the rental company whether it’s permitted. Not all vehicles are suited for off-road conditions.

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

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.

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.
