BMW has been pleasantly surprised at customer demand for the wagon version of its latest M5. Sales of the M5 Touring once outpaced those of the sedan, with the two now aligning on a near 50:50 split. And that success could potentially spawn more wagons in the near future. Speaking to Bimmer Life, BMW's North American Vice President of Product Management, Michael Keller, said that BMW "will look into" bringing more wagons to the US where it makes sense. That's great news.
