Some may give you a hard time. However if you like it put it on. You paid for the Msport options so place one more where you want. Placing an X5M on a standard X5 is a poseur. Placing an M3 on a standard 3 is a poseur. Placing an M5 and fake exhausts on a 528 is a blatant liar. Every enthusiast knows there's not an X3M and you're not placing it on the rear anyway. You're not trying to deceive anyone. I think it would be subtle and fine. On the bottom grill would be even more subtle in my opinion. I stuck my BMWCCA logo underneath. Your car to tweak as you see fit.
