I just got mine tinted with Llumar. I could of got it tinted for $175 if I got the classic or whatever its called...lowest quality. But as you step up in coverage the cost goes up. It ended up costing me $300 out the door for the Llumar Formula One Pinnacle. It protects the most from UV rays and blocks out the most heat. It also does not use any metallic particles that could possibly interfere with electronics i.e bluetooth, SAT radio, etc. All in all they did a great job and have done a great job on other Z's in the area that was the deciding factor to me. I could of taken it to the installer that did my truck in 3M but they scratched the hell out of the door jams getting in a out
. It boils down to a place you can trust to do the work honestly. I will pay a little more to know they will take care of the ride while they are working on it and not scratch it.
