PENNDOT vehicle question, if I can’t ask here please direct me.

So if there’s a “barn find” vehicle in the garage of a house where someone died, it’s in my neighborhood. They’ve been dead for over a year, no one came to the house to clean it out and it hasn’t been put up for sale. The person who lived there lived alone, I never saw visitors come to the house. My question is the vehicle is from the 80’s and was last registered in 95. It has a plate on it but no readable VIN. How would I take ownership of this vehicle? I’m willing to pay a reasonable amount, but I don’t know how. There’s no probate lawyer or executor. This person was a hoarder. Nothing was ever taken after they died or I would have just asked that person. Who do I talk to? The vehicle has been sitting in a dirt floor garage for years. It’s very rusty, I just want to try to fix it up, it’s going to cost a lot to fix up. So I don’t want to pay a lot but I do understand it won’t be free.
