Actress Kyung Soo-jin converted a Kia Ray into a camper, sparking a surge in interest for such modifications. The Kia Ray, a microcar with a height of 1,700 mm and a wheelbase of 2,520 mm, offers enough space for one person to sleep after removing the rear seats. The car starts at 13.4 million won, with conversion costs bringing the total to around 20 million won. The model is popular due to tax benefits for microcars and low running costs.
