There should be, and I agree with the above. It would be a real shame to a ruin a rust free car in the form of cut-off body parts if it could be legitimately titled instead.
If the car was really hers to sell, then you should be able to get the proper paperwork to get it legitimately titled. Keep in mind, however, that just because a buyer calls a car "abandoned", it doesn't make it so. It's not up to the buyer to make that distinction.
The NV DMV guidelines state that abandoned vehicles can be removed by a licensed NV wrecker who fills out all the appropriate paperwork and places a lien against the vehicle owner. And if the vehicle was on private property, there's more: "If an abandoned vehicle has been towed as a result of a property owner or property manager's request to remove an abandoned vehicle from their private property, a "PRIVATE PROPERTY ABANDONED VEHICLE RELEASE" (POR) form is required by the Department as proof of a private property abandoned vehicle impound."
But back to the original belief that "she" owns the car. You can't "abandon" your own vehicle on your own property. If you're there, then it's not abandoned. You can have your own car hauled off as scrap (and there's forms for that too), but you can't proclaim your own vehicle as abandoned. It's a divide by zero error.
So if she truly owns the car outright, then she should be able to sell it to you with the proper paperwork. If this vehicle changed possession (note that I did not say "ownership") with some cash and a handshake between two people, neither of whom names appear on the title, then it didn't really change ownership. If that's how it works, then I could "sell" my neighbor's old car that hasn't been titled for ten years.
And there's a name for places that cut up and sell parts of a car that they never truly owned....
