Well, I got the 1:18 mini-me of my car from Tesla. It's exactly as the online pictures shows, so unfortunately some of the missing/incorrect details are there on the actual product. Overall I'm pretty happy with it though, as it is very nicely detailed and looks good.
The missing/incorrect details as far as I could tell are:
-No rear window defrost lines. I'm pretty sure just about all 1:18 scale diecast cars in this price category have those, so not awesome to have it missing. Hell, I actually have some 1:64 cars that have it. I guess you just pretend that the rear window is so dark you can't see any lines.
-Missing "Dual Motor" emblem in the back. They weirdly skip this for the other cars too.
-Extra tow hook cover on front bumper. I wonder if they confused it with USS???
-No USS detail but the front doors cards doesn't have the latest trim styling, so kind of inconsistent with the real production cars, since I don't think this combination exists. (I have an unofficial 1:24 Model Y that DOES have USS detail, so it's not a case of USS detail being so small that it should just be skipped)
-No Matrix headlights. At least I don't see the round light at the outer edge.
-Center screen is entirely map. Unless one of the pre-V10 UI allowed the entire screen to be map.
I probably missed other details, but whatever.
Anyway, if you're into model cars, I think it is a pretty good representation of the Model Y Performance despite the missing/incorrect details. I'm just glad they finally made one for the Model Y.
