impressive... nor is your elitist attitude. You should look into some philosophy to supplement your economic theories, like the restraints on what a man can do with an apple fallen from a tree on his own property... The rights of ownership... I'll give you a hint - as long as he doesn't throw the apple at someone's face, he can do whatever the hell he wants. And if a neighbour doesn't like the look of this apple? Don't look at it.
It's too bad that not everyone is choosing the same route with their cars as you have. This in itself does not make someone lower class. You will never be able to make every Z owner in the world keep their cars stock. Deal with it.
