Meh... it's just a badge. Do whatever you want, as long as you're not intentionally trying to make it seem like your car is more expensive than it is. I say that you can even use an ///M badge if your car is better than an M135i, as long as your badge reads something like "///M 135" or "135 ///M" or something else to make sure you're not trying to pawn it off as a 1M.
