Other mistake: When Tony drives the city model home in his convertible, the wind would have blown away a lot of dust. When he sets it up at home, he blows a thick layer of dust off it.
Suggested correction: The wind would have blown dust off the exposed sections, but it was stacked. There would still be dust on other parts of the model.
I just believe the wind would easily be blowing strongly throughout the entire thing. It's not aerodynamic nor wrapped in any way, plenty of space between the pieces. I highly doubt dust should be present on that.
Trivia: Not sure if it was done on purpose, but when Tony and Happy are sparring and "Natalie" (Natasha) walks in, the song playing is "Magnificent Seven" by The Clash. It just so happens the Avengers (or the Avengers Initiative) are made up of Iron Man, Black Widow, Hulk, Thor, Captain America,, Hawkeye, and Black Panther.
Suggested correction: I don't really think this constitutes trivia. I don't see the connection. Is there some significance to the lyrics I'm not realizing? Or are you suggesting that there are only seven Avengers in the MCU? Because if so, that's not really true at all. (It's not even true in the Avengers comics, which frequently shifts characters around.) Especially as when this film came out, Black Panther wouldn't be introduced for another six years. Plus that completely ignores characters like Ant-Man, Wasp, Doctor Strange, the Guardians of the Galaxy, Scarlet Witch, War Machine, Falcon, Vision, Captain Marvel and Spider-Man, who join the team at various points during the franchise. I think this trivia is stretching at best, and trying to create significance where there is none.
Which is why I wasn't sure if it was done one purpose, or if it seems significant. However, when Fury and Tony are talking at the end and you see markers on the map, there's one in Africa where Wakanda is, suggesting Black Panther was part of the Avengers Initiative, whereas the others weren't.
Stupidity: Why in the world would Tony of all people leave his old suits in storage WITH the miniature arc reactor still inside the suit? This would have served no purpose to Tony since he already has his own arc reactor in his body.
Suggested correction: This is a question which is easily answered; Tony had the idea of putting someone else in the suit (like Rhodey) himself. Plus, it's logical to think he has built multiple miniature arc reactors, after the events of the previous movie. Plus, he can probably just as easily switch from arc reactor to arc reactor in his chest when changing suits, so he has a fully powered arc reactor ready in each suit.
