Hi, newbie here.
Just got my 2017 X3 M sport x35i, alpine white! 
I`ve included a pic of the exact same vehicle.
I am thinking about some mods and could use your input. It comes down adding to real carbon fiber trim and m colors (using non-oem parts) and a big change to the grill:
Carbon Fiber:
door handles, side mirrors, fin antenna, grill frame, trunk/hood emblems and rim caps, tire valve caps
M colors:
door projector lights
small badges (either just tricolor, //M, or carbon fiber with tricolor)
-potential locations include above the side signal light, on the gas door, and/or near logos such as the xDrive 35i
Grill:
carbon fiber frame with glossy black double slats
plus/minus tricolor
I'd appreciate your thoughts about this.
Especially, what do you all think of tricolor grill vs not? I love the look but worry it implies M performance engine and 'poser'? I do have a 35i engine, but not quite the same obviously.
When I get a better idea of my plan, I may post a photoshopped version of what I propose if there is any interest
Thanks for reading and any thoughts you may have!
