I like that. Looks great. The exterior looks absolutely gorgeous. The headlights and clear markers are a great look. The steering wheel cover needs to go though! Haha. But the cloth killed it for me. It looks really out of place compared to my leather one. I'll try to post a picture of mine here in a bit.
My M3 bumper was a polypropylene one too. I liked it because it was lightweight and really durable. I was in a small accident where a guy pulled out in front of my and I t-boned him (his fault) and the bumper took the impact with no damage to anything else. It was very cold out as this was in November I believe, so the bumper cracked and parts shattered, but my body shop said the bumper did exactly what it was designed to do. I paid $600 CDN for it. The one that I have on now is an actual OE M3 bumper from BMW and its triple the cost (paid for by insurance).
