Cars are enormous in Korea that’s why you won’t be surprised anymore if you find them parked in the streets. They are on different sizes, colors and brand. There are some cars with whispbar roof rack on top of their car, this accessories are helpful so you can carry a big load on your car during a road trip, most Koreans love to do picnic and road trip travel so it is really a must especially if you have a lot of kids. I even saw some cars with case shaped like boat in top of their roof dunno what is inside the case, it is either golf clubs or fishing tools.
If you are planning to buy this kind of accessories but you have hesitation forget about it because whispbar roof racks fit into different type of cars, inexpensive and easy to install.
