Well, the info i have is slightly different:
A4 1.8TFSI - 5.5-6.5 million
A4 1.8TFSI S-Line package - 6.8 million
A5 Coupe - 11 Million+
A8L - 17-18 million+ (fully loaded)
Q7 - 11.5 million+ (fully loaded)
From what i hear from their sales guys in Karachi or Lahore. Best seller is the 1.8TFSI as it just has everything money can offer. Plus they at least come standard with real leather, vs the artificial leather MB has to offer. Also, their after-sales is just out of this world. My buddy who owns a Q7 had an issue 2 weeks ago with his car. Slight issue with the steering wheel, and it was midnight. He picked up his phone, called the country manager directly. He was having dinner somewhere with friends. From what i hear, he left the dinner and came over to see him. And mind you they are not even friends. There was a problem with the key, and he had made a mistake. He showed him how to do it, and went back to his dinner. Try calling the MD of MB or BMW in Pakistan 
Anyway, my point being. They are new compared to the rest, but they do go out of the way to help clients. My verdict for that: excellent
Just wish i could afford an Audi. Maybe soon they will have some used A4's in the 3 million range. Then i will get my hands on these beasts
