I like that especially if it hides scratches better.
Quite pricey though but made in Germany so maybe can be sourced there for less.
If need a new top I'd consider this (my top has a sewn in screen, still got plenty life innit).
My rear window is redundant anyway as at night/winter I have the mirror dipped always, too much glare.
Miss the auto tint rear view mirror my 330i had.
Need to do something with the side mirrors, they need a tint or something to lessen the glare, our cars are just the right height to catch most other headlights in the sweet spot to blind you!
