So working in the dealer world, it is possible to take ownership of an abandoned car. Here in MI, you must take pics of the car, and the VIN to the SOS (DMV) and file an abandoned car form. If the PO doesn't respond in 45 days, the car is yours. We had a tow company that would make it a habit of going out on the freeway and picking up cars for the state police on the freeways. They would give the owners 10 days, then file the paperwork. He actually made a pretty good living off of it. There was one that went 48 days. The dude came down and threatened the tow owner with a gun...it was ugly. (Might I add that was the fourth time I had a gun pointed at me by someone other then a police officer!!) Needless to say, I walked away and called 911....after everything was done, the tow owner called him and let him have his car back.
