If you go for the tints dont have the front windows done. Police up in Scotland pulled me over, checked the fronts and said they were too dark. £60 on the spot fine, 3 points and the car would have to be uplifted as it couldnt be driven. In the end he settled for me removing the front tints, which we couldnt do, so he let me off.
When I got home I went to get a lighter front tint, only to see a new Discovery having his fronts removed, due to the police advising him!
Tint man said any additional tint to the front is a no, no, only what they came out of the factory is legal.
Trouble is the insurance companies can use this to refuse to pay out, as I was advised up in Scotland.
