with how low the car sits as is, and how BMW paint is notorious for getting chipped up pretty badly... i think its a big mistake to take it off.
That's like a phone case or screen protector... I wanna take it off all the time as it gets beat up to expose a flawless image, however i know it will only lead to my demise as it will get scratched and dinged up as soon as I did. I like knowing that underneath its like new.
