My first project in my 95 Vectra is the sagging headliner. Here is what I am thinking about doing to fix it.
The headliner is coming apart where the seam strips are. I intend to buy some wide white plastic molding strips from Lowe's and screwing them into the ceiling with short screws. I know that the headliner has a foam backing but I am not sure of the thickness of the board the headliner attaches to.
I figure this will work because the A/C vents are attached to the headline board using screws and visually it appears that there is plenty of space between the headliner and roof.
I just don't want to scrape all of that foam backing off at this time. I want to hit the road!!
