In Tianjin
The E66 7er was modified into a G12 LCi 7er by changing its front and rear ends. This is a popular modification method in China and also exists in other parts of the world, such as Russia.
This seems to be... just some people with not much money so they buying second-hand old luxury cars and then modifying them to pursue so-called "face",in China we called "Mianzi".
