ekw said it perfectly its your car do what you want and i agree with that completley. personally im not a fan of the purple at all. the gold i like. or even what you have now. personally if your windows are tinted ( which i think they are cause your from AZ ) and i was walking by your car randomly i wouldnt look inside if you had tinted windows id check out the outside so it doesnt really matter if you have a purple headliner or not.
