Well the X4M isn't even a drivers' car and this is a 2019 model that he got on the cheap last year and then put this chavvy plate on it like it's some kind of racer lol. What a loser. If you're that much of a big man get a proper sports car or pipe down and don't embarrass yourself
I don't think the plate shape is illegal, as long as it meets the minimum size requirements. Cars like Jaguars and Land Rovers have large, odd-shaped rear plates to fit the recess in their boot better, a stylistic choice.
