Hi all, I just brought my X home last night... Oh so happy! I tried to sleep in it but the Wife-to-be wouldn't let me. I have the car in Sterling Gray and would like to get the monochrome black grill. I've seen some members have done this and am wondering if anyone has the part number and or the cost? I'm also planning to swap it myself. Have any of you done it? Any warnings? Thanks in advance!
