Build quality was better than what I was expecting. When you set the bar low, it's easy to be pleased. No real issues (that bother me) on mine.
The bottom far edge/corner of the passenger headlight protrudes maybe 2mm from the bumper but it's minor.
The drivers side door where the front fender, A-Pillar, side mirror all intersect you can see a bit of half/lightly painted blue in between the panel gap. It's like looking throught the gap to see the panel behind the gap just has overspray blue and not fully painted. a quick touch up paint and fine tip detail brush coud fix it.
Tesla still having issues with the spoiler separating from the adhesive. My drivers side of the hatch spoiler is loose. Probably best to just buy some BMW Betalink adhesive and reattch it myself.
