You still have the option of deferring the balance payment until the next allocation. They will not "assemble" your car until they have the full payment, so if you want to ensure that your car is "manufactured" in 2025, then you can defer to the January allocation.
I expect that they'd push a lot to get the balance payment right now because most people avoid getting a new car around this time so they have wasted capacity at the assembly line and they'd want to keep it occupied as much as possible, but at the end of the day, it is your choice when you want to make the balance payment.
