you have only 2 options in so cal..that i know of. one is Song's auto tint in LA and the other is Perfect Tint in HB. and the price is around 475ish. i got mine done through Perfect Tint and they drove out to my house to tint my 330 and the ls430. they did a great job
BTW i got the Huper Optik ceremic 40s all around looks prefect.
