I like the idea, but unless it has a third row--and perhaps a sliding door--I don't see the advantage over something like an X-1 or X-3. (Then again, I never saw the advantage of an X-1 over a wagon like the 325iT or 328iT)
If BMW could come up with something like a Mazda 5, that could be a winner.
I guess Bandit represents a popular school of thought about minivans. But the reality is that lots of guys with testes--and a wife and kids to prove it--drive minivans, which are much more efficient carriers of people and stuff than SUVs.
Let's also remember that while there's no market for this kind of car in the US--Ford abandoned plans to import the larger version of the C-Max--cars like this do sell in Europe where space and gas are at a premium.
