Legal analysis: Mortgaged vehicles can apply for property preservation, but when the mortgaged vehicles are executed, the mortgagee has the priority to be compensated.

Legal basis: Provisions of the Supreme People's Court on Several Issues Concerning the Execution of Work by People's Courts (for Trial Implementation) Article 40 The people's court may take measures to seal up or detain the property owned by the person subjected to execution that others enjoy the mortgage, pledge or lien. The proceeds from the auction or sale of property shall be used to pay off the creditor's rights of the applicant executor after the mortgagee, pledgee or lien holder have priority in compensation.
