New rule about junk vehicles at my yard apparently.

A bill of sale don't mean squat when contested in court.
Any Monkey with a crayon and twelve pac wrapper can write a bill of sale and have it notarized but ONLY your state can issue title to a vehicle
Vehicles have one title that matches the VIN , and the name and lien status on that title is the final word until they are changed by the DMV.
Some of us have learned this the hard way some have yet to.
A call to the cops or DMV with a VIN could save a lot of trouble if you are in doubt.
Old dude had a post or two about how much grief this can cause way back if I recall.
This kind of info is no secret and needs to be right up front for all to see
