I’ve got an old beater that I’m driving around and I needed to take out the headliner. I don’t want to put much money or time into this project, because the car is simply not worth it.
I removed the shell when I took out the headliner, and it would be cool with me just to leave the whole thing out of the vehicle.
My question is whether or not the shell serves a purpose that would make it worth my while to keep it around. Does it provide sound or weather insulation of any sorts?
