Wrinkly doors cards - production change

[TonyS9]

I'm just rebuilding the car after painting and had a wrinkly door car from the donor door, my originals are not wrinkly atall so I thought I'd investigate. I also notice a rather ratty speaker install in my car, but a much better one in the donor.

My car: 95 940 2.3 SE turbo estate
Donor: 96 940 something lower spec with manual uncoloured mirrors

It seems the later car has the vinyl cover of the door car clamped up at the edge with a metal crimp over the top. The metal crimp is in 3 sections, leaving stress gaps where the wrinkles occur that pull away from the edge. If they had been continuous or long enough to butt together the wrinkles may not have occured.

In my earlier car the vinyl is wrapped and glued all the way around the outside of this continuous metal crimp with gaps only on the underside for the door retention clips. Clearly the production changed has caused the wrinkly problem.

The speakers they seem to have run out of the proper rivets in 95 and restorted to wider one pushing in from the backside and using only 2 per speaker instead of 4. Volvo need to goto cost reduction school, this is not the way to cost reduce a high end luxury car! Its a disgrace if they did this deliberately, and even worse if they allowed production to continue like this because the proper parts were not available.
