Is removing parts of a car, such as the stereo and the seatbelt buckle, before selling it for commercial purposes considered among the forbidden acts of shortchanging mentioned in Allah's saying, "Woe to those who shortchange [others]"?

Defrauding is consuming others' wealth unjustly, like someone who reduces the agreed-upon measure during a sale. The scenario mentioned in the question is not considered defrauding in the Shar'i sense, and it is permissible to sell the car without the mentioned items, provided there is no deception or cheating.
