Car Hire in Apkujŏngi-dong, Seoul, South Korea

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.

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.

Always keep your rental agreement, identification, and insurance information easily accessible during your rental period. This can help resolve any issues quickly.

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.

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.

If you’re sharing driving responsibilities, check the regulations regarding additional drivers. Some agencies may charge extra fees, while others 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.

Select a pickup location that is convenient for you. Some rental companies offer locations within the airport for quick access, while others may require shuttle transportation.
