Car Hire in Chŏngnŭngsam-dong, Seoul, South Korea

Prior to booking, read through the rental agreement thoroughly for any hidden fees, such as airport surcharges, additional driver costs, or penalties for late returns. Being informed is essential for budgeting.

Before booking, check for any promotional offers or discounts that may be available. Many rental companies provide seasonal deals or discounts for early bookings.

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

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.

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.

Before leaving the rental location, check that the vehicle is stocked with essential emergency supplies such as a spare tire, jack, and first aid kit.

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.

Make sure your rental agreement, identification, and insurance details are accessible throughout your rental period for easy retrieval if needed.
