EV Tax Credit Changes

I have a contract to purchase an EV that I ordered before the Inflation Reduction Act was signed.  I've read the transition language, and their seems to be a lot of confusion on what a "binding contract" is. In Virginia, if you have a non-refundable deposit and a signed contract to purchase a vehicle, does this make you eligible for the 2022 version of the credit?  The IRS language also gives an amount of 5% of the contract value - does that apply to all states?
