I just saw a car ad on TV. It showed two identical 4WDs side by side. One was labelled "2007", the other "2006".

The premise of the ad was: the 2006 model is great value because you can't tell it apart from the 2007 model and it is so much cheaper.

This of course prompted the question: if no one can tell the difference between the 2006 and 2007 models, why bother making and selling a 2007 model?

Could this be yet another cynical and wasteful exercise in greed?
