An interesting finding, Tesla gray market in China http://club.autohome.com.cn/bbs/thread-c-2357-29458971-1.html
Similar to all other luxury brand cars, the official China quote usually can't meet the demand. So a lot dealers buy cars from US, then ship to China for sale. Here is an example from the grey market inventory in Tianjin City. All those will be counted as US sale.
Note: the user interface is english, so it's US version instead of Chinese version.
