When I was living in LA, one of my cars was a black 560SEL totally limo level tint on all sides. I never got stopped once out there. The secret I think was the car's communications system appearance. I had a company install a full "presidential limo" type antenna system on the car, there were 6 antennas in all. Any cop seeing it would think the car had to be transporting an ultra important VIP. I could park it virtually anywhere and not get parking tickets either since it had such an official look.
