I booked the car on Trip.com because it was reasonably priced. However, I was worried because I couldn't find any reviews for the company. However, I was able to contact them via KakaoTalk, and the person I spoke with spoke some Korean, so it wasn't difficult. However, I was disappointed that even though I had checked my reservation for an ETC card, the company didn't provide one, so I had to use it without one. Also, I was a little disappointed that I booked an Alphard but received a Vellfire, which is a similar car.
