I dunno the renders are starting to feel very accurate... look at the bottom portion of the grill area in the spy pic from Spain:
Now look at that same area in the render:
The "meshy" black plastic portions on either side of the central grill area pretty much align with what we see in the spy pic. Just picture some the grill portion with some body color covering and it aligns pretty well with the render... except the render has horizontal grill slats (as seen in the other M3 spy pics) instead of vertical seen in the spy pic above.
