Study finds men are from Lincoln, women are from Volvo

In marketing, companies always track the demographics of their customers to identify shopping trends. They look at age, geography, income, and many other factors, but perhaps none more so than sex.

The auto industry isn't immune from this -- not by a long shot -- and it's drawn a number of conclusions about today's shoppers. For example: women are practical, but men get better deals. Men like a showy ride, women prefer one with smarts. And so on, and so on. Vive la difference.
