There are a lot of cool stories that could be told. Some vehicles motors blew up in roll test before they ever left the plant were I work and I don't think anyone put a VIN number on the new motor after or during the motor change. Test drives use to go on a lot. Smokie burn outs at lunch with a bunch of other workers. Having drag races on the ring road around the plant and running out of gas and just leaving the vehicle right there and walking back to your work area and not telling anyone about the vehicle. It was more important to just keep the line moving than to care if some vehicle got all its VINs. If it was workers vehicle being built it got plenty of extra care and undercoating and some extra goodies, such as better suspension parts and up graded performance parts. Now it is very hard to upgrade do to Computerization and unit builds from other plants that come in completely built and ready to be put into the vehicle.
