My new-to-me car still had the plain glass from the factory and I knew that I wanted to darken it, not just for privacy but also to block out some of those darned UV rays that seem to be everywhere these days. A quick search of the Yelp and I'd found my place after reading Sarah's review.
They quoted me a price over the phone and I made an appointment, dropping of the car and heading nearby for a nibble and stalking some places to review later. When I returned, I could see that the guys had done a completely professional job that, even with the lifetime warranty, will last for quite a long while. No bubbles, no missed spots and the tinting is carefully tucked under the various gaskets and things so that it won't get peeled.
A little on the spendy side and perhaps not as dark as I wanted, but I'm very pleased with the quality.
