im definatly not one to preach mate
BUT.... tbh it doesn't matter what you say they did this, i did that??, you know your plates are wrong just from what you have posted on here??? as for the windows if there is tint film on your drivers pair then your done! factory tint is 25% a film over the top will obviously make it darker, with things like this your and easy cash cow for them, i know as im speaking from a lot of experience of this exact same thing with my previous car, you take your chance buy running like this and its just a matter of time before you get stopped.
sorry to sound like a grumpy git
the police will ALWAYS win, learn from this mate and put it down as experience
get yourself a nice bright interior and you wont want to tint the windows
