The wagon is a win.
My humble prediction is that the wagon is a complete win for BMW. In addition, if it were brought to the US, it would sell like hot cakes. It's hot, it's fast, it's got all wheel drive, and it even appeals to all those who are driving very old MB diesel wagons with the original MB 4-matic. It would eat into SUV sales because anyone who has tried to load any sports equipment onto the roof of an SUV really wants a fun wagon. Did I mention it's hot?
