Go to the HuperOptik website to find a local installer ... I had my car tinted with this product and I have no regrets.

When you do find an installer, make sure and ask their opinion of it. The local guy I went with has a great reputation - he's been tinting for years, and folks drive many miles to use him. He was more than willing to sell/install Hüper Optik, but after chatting with him for a while, I decided against it.

You can get excellent quality tinting, using non-ceramic tints, for almost half the cost. I had my E320 wagon done with Suntek Infinity OP for a little over $300, with a design similar to this S Class - progressively lighter, back to front. Hüper Optik would have been in the $550 range. Non-wagons would obviously be a bit cheaper for either.

And, at least for me, the cell phone/GPS/garage door claims are bogus. Both work fine for me with the Suntek metallic tint.

Another issue with Hüper Optik - per the installer I used, it's much more difficult to install. Make sure and check references/see some examples of the installers work if you go with the stuff...

I just got a quote from the Only installer of the Huper Optik tints in the NYC area. For my 420sel- It will cost a whopping $450 for ceramic, labor included to do the job. The person also reccomends that If I do not want to spend that much, he can install non-ceramic for $225, half the price! and still have the same warranty. He said the Huper Optik is the best and most expensive tint I can put on my car.
