After 9 months of indecision, a lot of reading this forum, and a bit of saving up, I am ordering today. I am glad I waited til MY14, especially if it is true you can use the bluetooth as well as the car SIM for the navigation at the same time.

On order:

Audi A6 3.0 (245) TDI Quattro S Tronic Saloon
Daytona Grey (6Y*)
Valcona Leather (N1V)
Stock wheels

Options:
Tech Pack Advanced (WB6), includes:
MMI Navigation Plus (PNQ)
Driver's Information System (DIS) with 7" colour display (9Q8)
Mobile telephone preparation - High with Audi connect (9ZW).
Audi Music Interface (UF7)
Audi adaptive cruise control with Stop&Go function including pre-sense front (PCG)
Audi side assist including pre-sense rear (PCH)
Audi active lane assist (PCB)
Exterior mirrors (6XE)
Head-up display (KS1)
Heated Front Seats (4A3) <--- last minute addition
Lighting package (QQ1) <--- last minute addition
Storage package (PAC) <--- last minute addition
Speed limit display (QR9)
Rear side airbags (4X4)
Tracking preparation (7G9)
75-litre fuel tank (0M5)

Options that were originally on the list but pulled at the final decision:

LED Headlamps - I think the Bi-Xenons will be just fine
Deluxe Climate Control - Would have preferred the digitial display but seemed expensive compared to the other options I threw in at the last minute.

Probably September for delivery.
