Used original BMW F30 trunk lip, part number 41007288757. Goes for $900 new, get it here for only 300 bucks! It's in great condition, my friend was going to use it for a project on his car and never got around to it. Has some scuffs and scratches, but no dents. Will fit 3-series sedan from 2012 to 2018, so 328i, 335i, M3. Also have the inner taillights for it for a few bucks extra. Pick up in Brooklyn, NY 11224 or can ship for about $250 (huge box).
