Start bringing in too much scrap vehicle parts and they will start demanding paperwork - one or two parts "everyone" has so no not worth it but if it gets to be a bunch they start suspecting crime and then demand paperwork.
Just saw it up so it's not obviously one complete car. Nobody cares as long as their ass is covered. You can get away with more if you're a regular and they know you and know you not to be sketchy.
Even if they know you they'll never take a full car body in one piece without a title or any of the other "open and shut case" violations of law because they don't wanna risk getting Randy Weaver'd because a good customer had government problems and became an "informant".
