Book Cheap Hertz Car Hire Deals in Mangui-dong, 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.

Research any toll roads on your travel route and understand the payment options. Some rental companies provide toll transponders for convenience.

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.

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

If you have a specific vehicle model in mind, consider rentals that guarantee the car type you want. This avoids surprises at pickup when you receive an alternative vehicle.

Be aware that some rental companies impose age restrictions or additional fees for drivers under 25. Make sure to check the company’s age policy when booking.

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.

Make sure you know the details of the roadside assistance included with your rental. This is crucial in case of breakdowns or accidents.
