Tesla registered 9,165 imported cars in South Korea in October, leading Mercedes-Benz and BMW, and needs 1,687 more to hit 100,000 for the year. Elon Musk responded to Tesla's Korean sales record with a national flag emoji. Tesla extended its lead as the top-selling imported car brand in South Korea last month, putting it within reach of becoming the first import brand to register 100,000 vehicles in a single year.
