There seems to be no used car market at present, but there are several used car sellers. As far as I know,' Dabo used car' is on 80 meters road (opposite to the municipal government), and there is also a good one in the east gate of Xingang Community. At least you can look at it for reference.
There is a second-hand motor vehicle market in Yingkou, which is located in the north section of the Fourth Line (Jin Niu Shan Street) and opens every weekend.
