I'm afraid you might not be able to get your car in mid December. I have been trying to book Honda City myself since September and everyone had been giving me delivery date in January 2017. I finally booked my car on the 18th Nov. and ETA for delivery is sometime in mid to end of Feb. 2017.
Their "inside news" is that production of city is hampered by the Honda Civic orders. Personally I feel that's pathetic. If the own is reasonable, people won't have to wait for this long to get hold of a car.
I hope you get your car on time so at least one of us is happy this year
