Car getting Repossessed?

It is technically totally legal to hide your car from repo men. It is not grand theft auto. You are the "owner" of the vehicle. Grand Theft Auto is criminal. Being behind on a car payment is a civil matter. The police only can interfere if there is a criminal thing happening, such as a repo man destroying the car. HOWEVER, repo men are legally allowed to take the car at any time if they see it, no matter where you are.
