Call him anyways. They work with dealers that can buy cars out. I know they were able to buy leases if you wanted to sell. Idk if he would be willing to do this, but worth asking.
Like you said it's worth a call.
I was thinking I may be better off calling a frum place where you get plates and registration done, and see what they recommend.
As I heard today from someone, what they did was...they left the title in the name of the original owner, and just swapped the registration and insurance to the new owner(a sibling).
As this is what that place recommended for them to do.
So it seems the best option would be to either gift it, co owner(though i'm not exactly how thats done.)or this last way mentioned above.
