I ordered my X5 4.4i without Factory Tint. I did not want to have a problem matching aftermarket tint with factory tint. I had 20% Tint put in all around, except winshield. Had it done for $270 total. Tint came with a Lifetime warranty against Scratches, bubbles, and basically everything else you can throw at it. It came out looking great. I was told, however, that the Rear Window was a complete Pain in the ass to tint.
