Most people want tint for the limo dark windows. I want tint installed to keep the car cooler and protect the leather but not get hassled by state troopers. Huper Optik has a ceramic tint that blocks 99%+ of UV rays but doesn't look as dark and doesn't block cell signals like metal films.
Watch the video on the huper website comparing it to limo tint..

I plan on having Express Tinting install Huper Optik tint in my 135i as soon as I pick it up from the dealer.
