I used to be from the school of thought that this marketing was "bad" or misleading the consumer. I think quite the contrary now. I've found that most buying behavior is ridiculously irrational and that marketing is effectively just exposing that human weakness.
BMW ad that shows a smart middle aged man with a beautiful women? That actually can be true. You don't buy a BMW for it's utility (getting from A to B), you buy it for the potential experience (getting from A to B with a hot blonde). Otherwise you go with the Smartcar. BMW marketing is just giving you ideas of what that potential experience can be. It's up to you to use the tool to create the experience.
