I was already suspecting it because of dollar rate hike, but was hoping IMC will increase price next year. Now I am hoping they don't increase price again this year. 
As per the terms mentioned on PBO; I will be liable to pay up to 10% of booking price in case of price increase.
I acknowledge and understand that prior to the delivery of the vehicle booked, the price of the vehicle may increase by up to 10% of provisional ex-factory price mentioned here in the PBO on account of vehicle specification improvements, if any.
