South Carolina insurance covers all vehicle windows with zero deductible and even covers OEM glass. So, the glass was replaced with a new piece of OEM BMW. The local company who did the work was called Clear View Glass, and the service guy (owner?) who did the work was named Jason. He was a total professional. He was able to carefully remove the glass almost in one piece, once the door panel was removed from the inside.
Later the same day, my wife had the aftermarket window tint replaced with new. Theoretically, maybe I could have tried to get insurance to pay for the tint, and they probably would have, but I didn't try. We had a bad experience with the original tint person we used, so we would never go back there (or recommend him for any work, ever). So instead, Jason from Clear View suggested the best tint shop in town, Palmetto Tint Shop. Palmetto doesn't carry the Llumar film we had on the car. Instead, they sell Huper Optik. The color match was right on the money and they installed it onto the new window without issue or drama. Supposedly the Huper Optik is more durable than Llumar and it rejects heat better. They had a heat lamp demonstration in the showroom and it was obviously better at insulating from heat. If you go to Palmetto, ask for Brian and tell him X5nut sent you!
