Hello again people. My last post was me complaining about a white "bucktoothed" g8 gt which i was prepared to purchase. I have since decided not to get it. I did buy a g8 though. Red g8 gt with moderately low mileage on it. The one issue the car had was a sagging headliner.... I did some research on how to remove our headliners and i feel as if the previous owner removed it improperly and popped the retaining clips. i have a sunroof and the area around the sunroof isnt necessarily flush. kinda sags on the back side of the sunroof. moreover the whole light fixture in the back is sagging enough that i can push it up and see that the fabric is overstretched because of this. Also the airbag cover clip on the passenger side front pillar is missing. if im correct in how i assessed the tutorials of removal, this is a spot that you need to remove to get that panel off and eventually the liner. has anyone dealt with a similar sag and was it simple to fix or did you need to buy a new $800 liner?!?
