Other mistake: In the very last scene of the movie, and just before Blondie shoots the rope that is holding Tuco on the grave's cross. You can see a car moving in the background, screen right of Tuco's head. (02:55:29)
The Good, the Bad and the Ugly (1966)
Plot summary
Directed by: Sergio Leone
Starring: Clint Eastwood, Eli Wallach, Lee Van Cleef
Blondie (The Good) and Tuco (The Ugly) are con artists, trying to steal as much money as possible during the Civil War. Angel Eyes (The Bad) is trying to locate a bank robber going by the name of Bill Carson, in order to collect his stolen gold. After a few scams, Blondie cheats Tuco by keeping his share and leaving him in the dust. Tuco eventually finds Blondie and drags him off into the desert, torturing him in revenge. Then they run into Bill Carson, who tells Tuco the location of a graveyard where his stolen gold is buried. As Tuco looks for water to keep Carson alive long enough to help more, Carson tells Blondie which gravestone marks the buried gold, and dies before he can say more. Angel Eyes soon figures out that they know, and all three want a 50% share of the gold, but only two of them will get it.

Suggested correction: I've just watched this scene; there's no car visible. There's a bit where Blondie prepares his gun prior to aiming, then the camera switches back to Tuco. To the right of Tuco, in the background, a blurry something can be seen for maybe a second moving right to left. The object is far too blurry to identify. There's no reason to believe it's a car. It makes more sense that it's a horse-drawn wagon.
Tuco: I'll kill you.
Man With No Name: If you do that... You'll always be poor... Just like the greasy rat you are.
Question: If Tuco seriously thought that The Man with No Name would shoot him, why did Tuco voluntarily stick his head in the noose? Death is death. Why choose hanging over gunshot?
