Tax law changes

Thanks for the reply!

I do have the VIN number. My question is wether I can get 2023 tax credit on this car or not. If not, I won’t purchase this car when it becomes available at the dealership and will think of another EV. 
The binding contract is a little vague for me since I haven’t signed any forms and the sales manager provided me a document for the EV TAX purposes describing VIN number, pre-order date, and my deposit.  They don’t know if that document is enough for IRS.
