Maybe that's too broad of a definition for this particular thread, but I think it's a good example of how marketing and sales are truly interwoven in everything we touch. Every product on the shelf is designed in this manner, to make consumers want it, or to convince them they need it.
It's a pet peeve of mine when people conflate advertising (hiring a seductive model), and some very narrow areas of marketing (identifying that successful, young customers like sport-luxury vehicles) with marketing as a whole.
I'd agree that from a product stand point it's not so different from a BMW, Lincoln or Acura... but it's not remotely similar to a Chevy. If you're interested in a sport/luxury sedan, Chevy has nothing to offer you. They can do sport, or sedan, but not sport, luxury and sedan simultaneously.
