Tax law changes

Hello,

I received a brief written document from my BMW dealership that states a preliminary buyer's order on 7/17/2022 for a 2023 BMW i4 , VIN xxx with retail price of $xx. I paid a deposit for this car but the car is still in transit and will be delivered to me in January or February. 

I was wondering if I can claim EV tax credit in 2023 since my deposit took place before the new tax law (IRA). Will my brief document be enough as a binding contract?
