I wonder why companies now days are taking their lower brands/models and tweaking them to almost out do their upper brands/models? Take for example the Corvette ZO6 and the ZR1. This article will explain my point. http://www.autoblog.com/2011/06/23/2012-chevrolet-corvette-z06-laps-the-ring-in-7-22-68-shaves-20/
One of the other companies I can think of off hand is BMW. Why they seem to neglect the M3 is beyond me. They come up with all these innovations, these new models, concepts, and the incredibly impressive 2012 M5, and yet the M3 is left to sulk in what little reputation it has left. Car companies, you really need to cherish what you have. Up your game with your models that are known for it.
