I posted this under the BMW forum because I didn't find a Mini forum, which is the brand of the car. Here goes...

I am a Cooper S driver and I was wondering what a reasonable price would be to get the entire vehicle tinted. I live in Texas and I know that the limit is 35 front, 35 back, any rear. Knowing this, I would like (preferably) the legal limit and the back as dark as possible to the point where I can still see through it well. I would like to have the iridescent tint where it is like a one-way mirror. What is that option called? Thank you in advance.
