2023 EV (Tesla) Tax credit

Tesla is telling me that their models qualify for tax credits up to $7500 for tax year 2023. I live in Texas.

I want to make sure I will get the tax credit if I buy a Tesla model either 3 or Y. Tesla EV was not in the drop-down in the 2021 and 2022 tax returns. Will I get the full $7500 tax credit if the gross income is around $127k filling as married and line 22 is over $10K? What about if the vehicle is not delivered until 2024 and I pay the amount?  Will I be able to use EV tax credit in 2024 tax returns? What about if there is no tax credit for Tesla models in 2024?
