I sold my car privately, and the buyer is now trying to return it because they 'changed their mind,' which isn't something we agreed upon.

If you suspect a genuine emergency, waiting a few more days might be an option, but this is not recommended given the high probability of fraud.

If you have any other contact information (e.g., a phone number from a previous listing), try reaching out through those channels.

Update passwords for your online accounts, especially those related to financial services and the platform where the transaction occurred.

Keep a close eye on your bank accounts, credit cards, and credit reports for any suspicious activity.

If you used a payment service with buyer protection, contact them to dispute the transaction and attempt to recover funds.

Report the scam to your local law enforcement agency. This creates an official record and may aid in investigations.

Report the seller and the listing to the online platform immediately. They may have fraud prevention measures and can ban the user.

Get a professional assessment of any mechanical issues to understand their severity and potential impact on resale.

Keep records of any problems encountered and any repair attempts.

If a return is not possible, focus on minimizing losses by selling the car privately or to another dealer.
