I just bought a 2010 fusion sport. Had the windows tinted at the "dealer special price"...$199. Not sure how great of a deal it was but it seemed reasonable and they did a good job, even got good coverage on the "dimples". Wisconsin state law is 50% front and 35% rear. Actually bought it as an Alaska resident which has stricter laws( 50/37%) but also avoided that nasty state income tax. I've gotten to the point in my life where I prefer avoiding the man as opposed to fighting the man...although I think the man should just leave me alone and let me tint the windows I paid for howevere I please! Anyhow, 50% tint is nearly worthless. Prolly protects from skin cancer and keeps the car cooler as well as protects the upholstrey...but not a privacy provider in any way and it doesn't make the car look much better. 35% is nearly good enough for looks and privacy, and all around I would be happy with it. We have a '97 BMW M3 as well 20% fronts and 15% backs. Looks great, excellent privacy...and not been ticketed...yet. The bimmer spends most of it's time in Ohio and Tennessee so maybe the laws are different. I know you're wondering why cars in so many states...it's a military thing. As a caveat...and I'm not trying to start a field fire here, but all kinds of people need tintied windows. Sadly, some people have xeromascia pigmentosum and cannot be exposed to light or it severely damages their DNA and skin. Some people get migraine headaches or cluster headaches triggered by bright light and really need darker tint. Some doctors are able to identify these conditions and write prescriptions stating a patient requires dark tinting to prevent these conditions (Like LT). And when cops pull people over people who have too much tint and have these conditions or a prescription for dark tint to prevent exacerbations of these conditions, they are legally protected. I also found it interesting that while there are laws that define how much light must be allowed in, there are few laws that state how "see through" the windows have to be...so maybe privacy tinting is an option without violating tinting laws or defrauding the healthcare system. Obviously I came up with this stuff after the horse got out of the barn, but darn it, the horse is caught now and the next time I need to tint wondows again it will be done properly!
