Agree. The M badge on the back is supposed to be for M cars only. (M3, M4 etc). A 4 series such as a 435i can have M Performance Parts on it (for example M Sport Line with M wheels, unique front bumper/grill to the M Sport Line, etc) however, it is not an "M4" and the rear badge should not be on it. This is for impostors! Not fair to the owners of true "M" cars.
Every time used these types of posts I laugh. Not sure why it should bother anyone. It's the persons car to do whatever they like.
The fact that someone putting a fake "M" on their car bothers someone who owns a true M, only proves that true M person purchased it to impress people or to pump up their own ego. How should anyone else's car make it "not fair" to the M owner?
I'm sure most M owners don't care what another person puts on their car, enjoys their M for its great performance, and knows it will take any of the fake M's in a race if need be. I highly doubt anyone looks at a fake M car, gets tricked and thinks "wow he owns an M, he must be a highly successful thrill seeker, I have to meet him!"
If people get a kick out of putting an M wherever they want, no one should care. Should the fact that my M-Sport has an M on the kick plate bother anyone? By definition in this thread, the kick plate probably doesn't classify as an M modified part unlike the brakes and wheel, etc, so why have an M on an average ol' kick plate? I don't know, BMW put it there.
People should just enjoy their own cars, stop thinking that people judge or look up to you based on the car you drive, and just get a chuckle out of another's " fake M", and stop getting bothered by it. These people are coming off more like a "poser" for thinking their "true M" will help their appearance and status in life, than the fake M guys.
