I did some work at a major car manufacturer years ago and one of the staff told me after she saw how they made one of the cars she would NEVER drive that band again.

She worked in the IT department and she said they just glue the panels onto the inside of the doors.

Well... yes. This was in the 80's and 90's and it was a cheap little car and my car at the time was made the same way.

A metal door and the very thin panel on the inside was clipped and glued into place. The panel is literally nothing other than cosmetic trim and noise dampening. If it came off, nothing would happen.

It's not like the wheels or outer panels were being glued on so her fears were not really founded on anything in my opinion. Just because she worked there doesn't mean she has insight knowledge that made her an expert on whether someone should drive their cars or not.
