M5 Cupholder

This is the twin cup holder sold by BMW for the center console.  You may have found it's not too sturdy on the center console and can get in the way while your shifting.  I've found it hangs on the door pocket perfectly and leaves my right hand free to shift.  It's very sturdy there and doesn't rattle.  Just be careful though to not close the door with an open drink or your door speaker and floor mat will get wet!
