Help... Vin #'s dont match

If you understood the joke that car fax is. You would understand. They only check private records nothing states a insurance has to be involved or any body shop "required" to report to a non existent entity. Say you wreck your own car pay the 20k bill your self NO law is broken and the car is fixed

Right back where we started. If your repairing the car involved removing VIN numbers then YES, a law has been broken. If not, then you're good. Yeah, you can remove the entire back half of a Duster and replace it with another car. If you don't involve the package tray VIN stamping, life is good. If you do, well, back to the start of this thread.
