are sold under the names Hwiparam, Bbeokgugi (Peokkugi) and Zunma: small and luxury cars, minivans, SUVs and pick-up trucks under license. Pyeonghwa has the exclusive rights to production, purchase, and sale of used cars in North Korea. Most North Koreans are unable to own cars. Because the market for cars in the country is so small, Pyeonghwa's output is reportedly very low. In 2003, 314 cars were produced, even though the factory could build up to 10,000 cars a year. Erik van Ingen Schenau, author of Automobiles Made in North Korea, has estimated the company's total production in 2005 at no more than about 400 vehicles. In summer 2006, the North Korean government magazine Foreign Trade, which advertises North Korean products, published a photograph of the Junma, a new luxury car produced by Pyeonghwa, which appears to be a rebadged version of the South Korean SsangYong Chairman. The Chairman bears a strong resemblance to Mercedes-Benz cars, which are favored by North Korean government officials, and is based on an old Mercedes E-Class design. In 2006, Pyeonghwa reached an agreement with Chinese manufacturer Brilliance China Auto to assemble its Jinbei Haise vans, which are based on an old version of the Toyota Hiace. In 2009, Pyeonghwa announced a profit on its North Korean operations. The Pregio and Pronto are also sold in Vietnam by Mekong Auto. Both are based on Hyundai vehicles. Mekong Auto has sold Fiat cars in Vietnam since 1995, and this relationship may have led to Pyeonghwa's building Fiats in North Korea. Pyongsang Auto Works In 1968, Pyongsang Auto Works in Pyongsang took over Sungri Motor Plant's production of Kaengsaeng and Kaengsaeng NA models: a modified Sungri-4.10 4x4 car (the GAZ 69-Jeep combination) and a modified Sungri-4.25 4x4 pickup. During the 1970s, it also began production of Taebaeksan and Tujaeng light trucks. Chongjin Bus Works Since 1974, the Chongjin Bus Works has produced the Jipsam 74, the Jipsam 86 articulated trolleybus and Jipsam 86 and 88 buses. In more recent years, it has produced modern trolleybuses styled in the Chollima 321 from Pyongyang. Pyongyang Trolleybus Factory Since 1961, Pyongyang Trolleybus Works has produced Chollima 9.11, 9.25, 70, 72, 74, 84, 90, 901, 903, 961, 971, 091, 316 and 321. It has also made some conversions of Ikarus 260, Ikarus 280 and Karosa B732/C734 trolleybuses. In 2018, the factory was modernised and now features modern technology such as CNC
