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

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.
