I am the one who asked the original question linked in the comments.
Anyway, unless something changed, you need to take your car to the Amghara traffic department:
I believe you need to find someone who will take it to scrapyard, but any tow truck with gladly take it off your hands as they will get some $$$ at the end.
There it will be inspected and you will get the papers. With those papers you go to the traffic department in your area, but they redirected me to the one in Jabriya. Maybe it depends where the car was originally registered. That is it.
