BMW has shown the 3 Series Touring for the first time, adding a welcome dose of dog carrying ability to its most popular car. It was only ever a case of when BMW unveiled the estate version of its most popular car, rather than if. In the same way, we’ll get a Coupé at some point, and a Convertible.That said, it’s almost certain that those two cars will be badged 4 Series, so that BMW can make them sound posher; the same principle makes Audi A5 drivers genuinely believe their cars are superior to A4s.
