On a legal stand point you can’t legally sell it or donate it as you don’t really own it given the title still from the previous owner. Contact whoever is on the title and have it transferred to you. Donating doesn’t work because the title needs to be transferred anyways.

You can be accused of theft should you attempt to sell the vehicle when it’s technically not yours even though you bought it.

Been there done that with a 2006 Jeep Wrangler from New York.

The best analogy would be like you buying a second hand iPhone that is iCloud Locked. You technically own it, but the person’s account is still on it and it won’t let you change ownership until the previous owner removes the lock. If the previous owner wants to be a dick, they can accuse you of theft.

Also, just sell it cheap. Might as well profit from it. $500 will motivate people to drive across the state for a running vehicle.
