Great E46 cup holder
Material Type: Plastic
Anyone who owns an E46 knows the cup holder eventually comes loose and that was exactly what happened in my case. I decided to change my entire center console from tan to black and decided to go with this new cup holder and it fit perfectly and it matched the console perfectly too. It hasn't come out on me at all.
