That's before you mention if 7000 cars went through production. You could easily have stored 7000 cars half way through production and finished them over a week.
Heck, they could have 8000 cars parked waiting to go through quality control, discarded 1000 that didn't pass and rolled out 7000 cars.
The number is largely meaningless without further qualification.
Yes -- I would love a clear definition of what "factory gated" means and then an accounting of which cars were already close to finished. But I doubt we'll get that!
