The vehicle is clean and it is very convenient to take over and take over in front of the airport terminal. However, it is not such a system in reality. The fuel cost and gasoline value of the vehicle set by the company are calculated at the distance of the vehicle operated by the company, and the fuel cost is settled when returning the vehicle. This fuel cost settlement system is very unreasonable. The driver directly pays the fuel cost to the gas station. I think I should improve the way I pay as much as I used to pay for fuel. I used Volkswagen Polo to go about 800 km on the regular highway, and I paid 107,000 won for fuel. (Taiwan's gasoline price was about 1200 won) it is a structure that generates fuel fertilizer revenue. I made a reservation, but if I don't agree with this system, I can't use a rental car, so I have no choice but to cry and eat mustard. I hope to improve the fuel cost settlement system.
