Grindhouse (2007) - 2 major mistakes

Continuity: Mike avoids colliding head-on with a pickup by swerving off the road into a farm field. He does this after passing a tractor and flatbed truck to his right. The shot changes and he is turning off the road into the field between the tractor and truck.

Deliberate "mistake": In 'Death Proof', a white 1970 Dodge Challenger is featured prominently in both the dialogue and as the vehicle driven by the three heroines. This is a homage to the 1971 film, 'Vanishing Point'. But a major plot point of the story hinges on a feature the car never had. Zoe Bell's character will lay on the hood of the car, held there by belts attached to the frames of the door windows, but no 1970-74 Dodge Challenger ever had such frames. The car is a two-door hardtop coupe, and it's windows are frame-less (and there is no reason anyone would want to custom add them). This error is magnified by the fact that they used chrome frames where black ones would have been far less 'hacked' looking. The entire error could have been avoided by simply installing a full roll cage in the car, using the bars at the A-pillars to attach the belts to.
