So, this is assuming the roll out to Greater London goes ahead, which I think it will. My car is 16 years old. It is compliant, but only just - the model after it isn't. Next year it will be over 16 years old, which is the threshold at the moment. Does this mean that next year it will not be compliant or does it not work like that? I've asked around and people say it's to do with emissions not age but the adverts are all around how old your car is. TIA.
