I would look at my own 2018 model 3 to see if I have that, but if I do, I will never (ever) be able to "unsee" it again, so im scared to look.....
If that was my car and I was still under warranty I think I would (politely) ask them to show me that spot on any cars they currently have in service, to show me multiple cars that have that cutout looking like that.
If they could show me multiple cars there that had that cutout visible then I guess I would believe them, otherwise, If they couldnt, I would (politely) ask them to replace it since it did not appear on other cars on their lot at the time.
Im scared to look at mine because I am out of warranty, but if I see that, I am going to want to replace it, even if I have to pay (lol).
Im trying to slowly back away from this thread to forget I saw that......
(lol)
