When we went to Dalian two years ago for my bro-in-laws wedding, the party consisted of 43 A6's, mostly C5, with the lead cars, including the one my wife and I rode in being C6's. her youngest sister has a B6 A4. Dalian itself has 3 Audi Dealer's. There is nothing strange looking about the VIN, they are in Roman characters.
(The attached pic is a view of the wedding party, extracted from the DVD).
