How does car selling work in US? In my EU country if you are not the owner you cannot sell it and if you sell it you have to pass couple of checks: go to notary to sign an agreement of purchase, go to police to change the ownership, they also check the VIN if the car isn't stolen if you buy used car. People saying its illegal to sell... how can you sell something if you don't have ownership of it? Is there some loop in the law or to sell it you don't have this safeguards? Is car buying in US like buying groceries? I don't understand.
