Please call that Additional ETO again and tell him categorically that you have nothing to do with his stance in the Court. And, that he must NOT quote you in front of the judge regarding the settlement with the immoral lawyer.
If you don't call him and say this clearly, he may misguide the judge that you have shown your willingness for this settlement through ETO Mardan.
ETO is answerable to the Court in this case. Let him give clarifications/explanations of his own without involving you.
Do also tell the ETO that it is entirely the immoral lawyer's own problem. And, you have nothing to do with it. Your concern is recovery of your car, only.
I am sure the judge shall never entertain this request. For this, the immoral lawyer shall have to complete the necessary formalities like registration of FIR against the criminal, filing of a criminal/civil suit etc.
