^ Agree. 20% is a perfect match -- although not legal in a lot of states. I got a tint ticket in my (other) car this year. I paid the $100 and kept driving
. My car registered 17% with the pig's meter (20% on top of factory tint). Even if I would have went with 35%, it would have still officially been too dark (probably read 32%). If he wanted to be a arse (and he was!), he still would have written me up.
