How can i get a title????

Depending on how friendly the person is, You could call the state police and explain the situation, and have them locate the previous owner.

Once the previous owner is located (provided they're alive) you then file for a Lost Title, the title goes to the owner, and then the two of you take a trip to the local license/title place (around here it's called PA Auto Brokers) and then transfer the title to your name.

It all depends on how helpful the cop wants to be though. They can't provide that info to someone who doesn't have connections to the car in question though. (I know, I spoke with them a while back about a Fury 'vert I found) They couldn't help me, since the car wasn't in my possession or on my property. But if it had been, I could have had them search for the previous owner.

There are still ways to get the title here in PA, but there's all kinds of leg work/running and paperwork to go through.
