When ordering mine, I had an S3 for around 1 1/2 hours, I'd already made my mind up that I was buying but took the offer anyway. I was supposed to be arriving at the dealership first thing and having the car all day. I had something else on and did not get to the dealer until early afternoon and as car was from another dealership and they needed to return it that evening.
If you are serious about buying then I'm sure if you ask they will do what they can. I suppose it all depends on if they have a car in the lot, or at another local dealer.
But if you dont ask you dont get.
