Bhuna50, to answer your question (and to keep up to date on delivery times) I was given an unconfirmed build date of week 5 in mid-December which was confirmed (still as week 5) at the end of the first week in January.
I have now been told that the car is in assembly this week so that is exactly 15 weeks from when the dealer sent the order to Audi.
I don't know for sure but I imagine that the cars take no more than a week to assemble. Then it's shipping, customs, PDI at the dealership etc. I have no idea how long that will all take but in my mind I am imagining mid-March for pickup.
We shall have to wait and see....
