This is the new PBO T&C this car was booked by cousin on the 27th i think
As per this
PS can change price any time
The price is appraised at the time of booking and changes in tax is customer liability
If the balance payment is made after the TDD then new retail price will be applicable
You are free to read the whole thing, but PS can issue whatever letter they want, if tomorrow they raise the price to 2.5 Million for the same will you pay the difference amount??
Honda and Toyota have a clause that price at the time of delivery will be applicable. (they also add that if you want to cancel the booking on the basis of price increase then you are free from the 10% deduction)
PS is bound to what they have signed and what you have Signed nothing more or less is binding on either party
