Ok, so I'm looking to get my BMW 325i windows tinted. In South Carolina, the legal limit is 27% for all front sides, rear sides, and the back for sedans. I contacted the tint company about seeing exactly how dark the 27% really is. It wasn't very dark at all, and certainly not the darkness I was looking to achieve. I've seen minivans with darker tint than what I was allowed to get on my sedan. Turns out that SUV's and minivans, according to South Carolina law and also many other states, can apply any darkness to the back sides and rear as long as the front sides have the 27% limit. Whaaaaaaat? How in the world do SUV's and minivans get special treatment? This makes no sense to me whatsoever. Anyone have any knowledge of why this is or has experienced similar stories?
