Most domestic products are in the form of joint ventures, mainly because moving to China for production and assembly can avoid the problem of tariffs, which control the price well, so the price difference is the biggest. In addition, from the car itself, the joint venture car may be different from the imported car of the same model in some details, depending on the brand. Some functions or configurations are useful abroad but useless at home. If they are made in China, they will be cancelled. Generally speaking, the joint venture company has the right to make minor modifications.

In addition, the domestic production technology and assembly technology are obviously a little worse. For example, the splicing gap is relatively large, the steel quality is different, and the level of different manufacturers is also high or low. The technology of larger domestic car factories such as FAW, Dongfeng, SAIC and GAC is better.

As for the problem of cutting corners, it does exist in China. In order to save costs, some joint ventures will deliberately cut corners on details.
