EV credit with binding contract

I reserved a VW ID.4 2023 right before the inflation reduction act on 8/14. I am expecting car to be delivered by Dec-22 or Jan-23. I also have a EV purchase contract (binding agreement) with the dealer.

Can you confirm I qualify for $7,500 EV credit as per the IRS rules before inflation reduction act (less than 200,000 units for this car)? Can I avail this credit as a part of 2022 or 2023 tax filing depending on when it gets delivered? What other documents are required?
