Make sure you receive detailed RECEIPT(s) for voluntarily-surrendering your:
car, keys, license/plates/registration, & title;
over to either your-dealer/lender and/or local/state-government.
Notify your-state BMV/DMV in-writing/on-their-forms of the surrender/transfer.
Obtain a clear/detailed-release/statement showing your:
car-loan-balance-owed/remaining, or forgiven.
Anticipate negative-impact on your-credit-report.
You might receive IRS-Form saying any-loan-forgiveness was "taxable-income".
