Car Hire in Karhyŏnil-tong, Seoul, South Korea

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.

If you're looking for extra comfort or features, ask about upgrade possibilities at the rental desk. Often, there are discounted upgrades available at pickup.

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.

Utilize GPS devices or navigation apps for easier routing. This can help prevent getting lost and contribute to a smoother travel experience.

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.

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.

Before finalizing your booking, check if the rental company offers free cancellation. This can provide peace of mind if your travel plans change unexpectedly.

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.
