Today I added the E46 coupe kidney grill with a little bending. I can still put my old grill back in case I change my mind. Here are more pics 2 3.
There is a small gap visible if you look at the grill from 180degrees, and also if you look directly from top. but other than that, it's a pretty darn good fit, i would say. the only thing questionable is if it matches the e36 or not
