Can't help but rest. Through Audi official website, I found out whether Audi has interest-free loan service. Audi is a German luxury car brand with four interlocking rings. Now it is a subsidiary of Volkswagen in Germany. 20 18 12.20, 20 18 list of top 500 world brands was released, and Audi ranked 5 1. In 20 19 10, Interbrand ranked 42nd in the list of global brands 100.
