Even in los angeles, you shouldn’t pay more than maybe 500 max for a good quality ceramic tint. All these luxury name brand ceramics don’t mean anything except more money out of your pocket. I’ve been in various cars with overpriced ceramic tints n didn’t see or notice any difference between what I’ve had before n chose to get again on my model Y. Rayno s9. You can do s7 for cheaper but s9 blocks out more heat and it’s noticeable. Where i went, they had a display sample with a heat lamp in a box and all 4 sides of the box being glass with different tint brands n the difference in radiating heat between s7 and s9 wasn’t night n day but it was noticeable. 4 door windows, windshield and back glass was $500. S7 woulda been $400. $200 more for the roof but i chose not to since my car doesn’t sit out in the sun. Being that prices for almost everything have gone up, this cost may have also increased since last march when i got mine done. Also, some places will go the cheap route and install the back glass in 2 pieces since they don’t carry large enough film to do it in 1 piece. This is important for some folks which will also alter the cost a bit.
