Founded in 1994, Doosan is a wholly-owned company in South Korea with export bases and strategic bases in Shandong and Suzhou, China, mainly engaged in the production of excavators, forklifts and engines. The performance of Doosan excavators in various indicators is decent, and it belongs to the middle and low end of imported cars, and the price is cheaper, but the overall quality is average, the after-sales service is poor, and the value retention is low. It is usually recommended to sell it for a new one after four years, otherwise the maintenance cost will be too high. In addition, Daewoo was acquired by Doosan, and its excavator performance was close to it.
