Would You Buy A Range Topping Mainstream Car Over An Entry Level Luxury Model?

The day could be fast-arriving when a new breed of car buyer considers a new generation of cars, and wrestles with a choice something like: "Hmmm, $30,000. Should I get that loaded Ford Focus, or this new mini-size entry BMW?"

Absurd? Not necessarily.

Luxury auto brands already are making a living in the U.S. on their smaller models — BMW's 3-series is the best example. Now, they're easing more into the compact- and even subcompact-size market segments and have begun to show teaser versions of remarkably small cars on the auto show circuit.
