Section 542(a) states that an entity in possession of property "that the trustee may use, sell, or lease . . . shall deliver to the trustee, and account for, such property . . . unless such property is of inconsequential value or benefit to the estate., meaning if their is no equity in the vehicle that belongs to him, the trustee will not demand it back as the property cannot be used to pay his creditors. Also, an attorney requesting the vehicle back should be in writing and I would not return the vehicle unless the court orders it, where you can show that you are contractually allowed to keep the vehicle.
Also Georgia law does not allow for a request to be made for the return of the vehicle, as long as you followed proper notice requirements you are fine.
If the bankruptcy court forces you to return the vehicle advise them of the contract and state to them you are using the vehcile for your personal use and the transfer took place as per GA law.
In cases where a secured party in possession may, after default, propose to
retain the collateral in satisfaction of the obligation. Written notice of must be sent to debtor if debtor has not
signed, after default, a statement renouncing or modifying rights. In the case of consumer goods no other notice
need be given, but additional notice to certain holders of subordinate liens. If secured party receives objection in
writing from a person entitled to receive notice within 21 days after notice was sent, secured party must sell
collateral under Code Section 11-9-504. If no such written objection is received, secured party may retain
collateral in satisfaction of the debt. See Georgia Code Section 11-9-505
