First ov all, heartiest congratulations on the booking alone. I don't know why m excited myself. A/T with SR is just the very ideal car in the local market many dream to buy.
As for the wait period, it is better to assume that the delivery period mentioned on paper is taken more seriously so that when the car arrives earlier, you get happier rather than it arriving later than your expectations and the opposite happening.
It is also true that calls from senior bureaucrats cause the car to be delivered quicker but then, i guess there have to be some connections in Indus too and not just an MNA calling to say 'm MNA Mr. Tutoo. deliver the car soon'. Someone i knew got their brand new Xli 2003 delivered within a month whereas waiting period in those days was 8-9 months because their relative was a top gun working with Shortcut Aziz and this guy knew the then Choreman ov Toyota Indus too.

But then, i do not know if he was the only lucky one or not.
