Mo. Rev. Stat. § 427.160
A creditor is not required to purchase collateral protection coverage or to otherwise insure collateral. A creditor shall not be liable to a debtor or to any other person for failure to purchase collateral protection coverage, as a result of the amount or level of coverage of collateral protection coverage purchased by the creditor, or because the creditor purchased collateral protection coverage that protects only the interests of the creditor or less than all of the interests of the debtor. Sections 427.110 to 427.190 shall not create a cause of action for damages on behalf of the debtor or any other person in connection with the placement of collateral protection coverage, and violations of these sections shall not be deemed to violate the standard of care under any common law cause of action.
