Where's the best place to go for window tinting in Dallas? Boardwalk Audi sent me to ProTint, but I'm thinking the prices might be a little high since they constantly get Porsche owners coming in.

Any places in town that carry Huper Optik?

I went to Artech in Euless. They did an excellent job. Very reputable - they do all the cars for Ballargian Audi, Lexus Grapevine, etc. I got 35% all the way around. You can go darker in the rear (20%), but I like it even. It cost me $250 but has a lifetime warranty.

Stay away from the metalized tints as they can interfere with the radio reception (integrated in the rear window).

They also offer Hupri Optik Ceramic tint - but it costs around $500 for the A4.

Pro-Tint is highly recommended by several NTAG members. I had my Avant tinted there and their work quality is awesome. Would not hesitate to recommend them. Worth the money for the quality.
