People want feel good, in this slave based economy where you struggle to get where you are, a car is one thing you can get that says to the world I am successful. You waste a lot of hard earn slave dollars on it so you get the best you can to make yourself feel as good as you can.

For some people when they can drive a boxy monstrosity it may make them think they are better than someone driving a little hatchback someone who doesnt have the same status as them.

You answered your own question it is just a status symbol.
