Not to blow your GB but... Do you guys know you can buy the rear window "screens" (rear sides and rear window - three screens)from BMW. Looks just like tint but you can take 'em out anytime you want to. I have them in my car and love them!
Here is what the screens look like... they ran me like ~110 EUR for all three screens.
