Why exactly?

I'm sure they replaced his old one with one of similar value, which with inflation just happens to be one with less bells and whistles? Does the truck get him to where he needs to go? I'd assume so, since it's a brand new truck.

Boohoo, it doesn't have an extra cigarette lighter for the passenger, or a fancy center console, or programable seat positions for multiple drivers.

I'm sure his company would be willing to take the truck back and let Mister P drive his own car. Then he can get whatever he wants.
