The X5MC has the same console as all X6's - it has the raised leather 'humps' on either side that encapsulate the console area. Normal X5's and the base X5M don't have them.
When you have the humps, the lights are run differently for some reason. Maybe they modelled it and it looked odd running the lights all the way down after breaking out from the humps
I definitely like the humps though - makes a nice knee rest for my long ass legs.
