Un-registerable Car

I recently bought a car off of Facebook Marketplace. When I took it in to the DMV to get it registered, they told me there were problems with the bill of sale and title, and that I would have to get new copies of both in order to register the car.

To make a long story short, I am unable to get the new copies because the guy who sold it to me is refusing and the police said they can’t help me, and told me to apply for a bonded title.

While waiting for my application to go through, I took the car to the shop to have it looked at. I found out that basically everything in the car was broken (transmission, engine, ac, etc.) and that it was basically totaled. I was also told that the car had no airbags. Due to these mechanical problems, I am unable to obtain a bonded title because the car won’t pass a sheriffs inspection.

I am wondering what to do now, as I can not drive or register the car. I know that I will not be able to get any of my money back, and at this point I don’t really care, I just want the car gone. I have tried to give it to a salvage yard, but they said they can not take it without a proper title, which I don’t help.

What do I do??
