Believe me when I say I've spent more time in automotive stamping / assembly plants then I care to recall. Not a vette plant to be sure, but after a while if you've seen one you've seen them all. I served on the front lines of trying to get the big 3 to use Aluminum on / in their cars to help meet the CAFE standards of the day(1990's). It was like (as a fellow forum member said to me today via e-mail) herding cats! Without any cat nip in sight I might add.That video shows about 20% of what you would see if you actually went to the plant to watch.
