It is a big VW thing. I did a full burberry headliner in my GTI..
$42 a yard. Lol.
The headliner in my truck is a simple plaid, it goes with my tan interior. Heres a pic.
It's not that difficult, remove the headliner, remove old fabric, it will leave this foam stuff. Get a wire brush, remove ALL the old foam (Very important, foam will absorb the glue and cause the headliner to sag)
Get new fabric, spray the glue (I reccomend 3m super) on the headliner board, let it dry to a tac, place on new fabric.
