If you want to hear from your Sales Advisor team tell them you plan to make the final payment via a bank cashier's check. They will contact you repeatedly and push you to set up an Automated Clearing House (ACH) debit * authorization with your bank checking or savings account. A few days for your scheduled delivery confirm the amount due and obtain a cashier's check for that amount from your bank. You can pay via a cashier's check even if you are able to elect for touchless home delivery. You just need to sign the documents that Tesla provides and return the documents along with your payment via the pre-addressed FedEx mailing envelope. In my case the FedEx was sent to the local Tesla Service Center. Depending on the laws in your state if you choose to make the final payment via a cashier's check you may have to send the final payment via overnight mail or FedEx delivery prior to delivery.
* ACH debit fraud is one of the oldest, currently fastest growing forms of banking fraud. Not that Tesla would intentionally commit fraud but all it takes is for an individual inside the billing or accounts receivable department to make a copy, later sell your banking information, along with other customers' banking information, to a fraud ring (the individual may be paid as little as $25 for your information.) All that is needed to initiate a fraudulent ACH debit transaction is the account number and the bank routing number information. I know this from personal experience. In 2019 a family joint checking account with a major bank was attacked by ACH debit fraud. I noticed unapproved ACH debit transactions on the bank statement, contacted the bank right away. The bank refunded the lost funds while they conducted an investigation, later confirmed the fraud. The banking advisor told me that unfortunately the only way to defend against additional ACH debit fraud transactions in the future was to close the affected account and open a new account. That means that any automated transfers, direct deposit that was set up on the old account had to be halted and then set up on the new account. All told it took me ~3 months to set things right and this was all pre-COVID-19.
