Need help getting a title

not sure how the laws are in PA, but here in MI, you would go to the secretary of state and apply for an "abandoned vehicle title"
they will run all the necessary checks on the car to ensure there is no one else claiming this case and you can title it in your now

Yup...I would just check with your DMV. Pretty sure in AZ you would fill the forms out for an abandoned vehicle. Takes a couple of months or so before a title is issued. From what I was told...from a somewhat unreliable source...here in Washington state you would need to contact the Highway Patrol...they would search for the previous owner...can't find him/her the Highway Patrol comes with a wrecker and disposes of it...
