Question: Is it legal (in Ohio) to transfer a vehicle title from one state to another without a vin tag and in this situation, a title not in the name of the actual seller? In Pa it certainly is not. Also, isn't the dash vin tag a DOT requirement?
I would be careful about proceeding to do anything with that car until this is resolved. I believe you are in possession of a vehicle that you do not legally own.
Good luck
