I deleted that post, but I think the plastic is different. Look at where the seams are different on left and right. The reason I deleted it was I saw the left top of the left rear fender coming down is like bent up from way up along the rear window seam. It just isn't right. In case you get a bunch of static from Tesla -- my last car was an Audi A8 and on the left rear door frame where it met the rear quarter panel, there was this 1" separation at the top. Only I would ever notice it. The other side was fine. It didn't leak, and it didn't cause any appearance issues anyone would notice from the outside. Only when you opened the door and looked closely was it an issue. I couldn't believe Audi quality control did not fix that during production. Hey, as long as it doesn't show, doesn't affect resale, and doesn't hurt anything, it is OK. The only problem is YOU know it is there.
