Hi olderbudweiser. As you stated..."...that was long ago". Things are different now than they were back in the day. Even when discussing pre-production vehicles only, as you just did.
"Just in time" scheduling/production has changed all that. Once the "pre-production" vehicles have cleared inspection/and the defect free production period (those vehicles do not go to customer orders), then "regular" production begins and every vehicle is scheduled for a particular Dealership as either a Dealer stock vehicle, or a customer factory ordered vehicle. And that is where they go. Once regular production begins, no one is walking in and saying "I want that one", no matter what their name is. Not because they could not, but because that is not done anymore.
Now, if we want to limit the discussion to those pre-production vehicles, then yes you are correct, and virtually any high level executive can get one of them. But that is a limited time and quantity of vehicles. And some may even be scheduled as Ford family or other high level executive vehicles, if they so desire (which sort of gets us to the previous "Priority Code 1" discussion

). But they are scheduled that way in pre-production.
However, nowadays, once regular production begins of customer factory orders, no one is walking into the factory and saying "I want that one" and driving out with it. And no one is losing their job for doing their job. Ford would be paying through the nose for an employee dismissal for something like that.
But again, while I can't be sure how long ago you were a plant employee, parts/component deliveries, scheduling, and production procedures etc. are very different now.
No one here needs to worry that anyone named Ford is going to steal their special order.

Hope that makes what I was stating more understandable. Plus...we are way off-topic now.
Good luck.
