"Wagons" are Chrysler Voyager, Renault Scenic, Citroën Picasso, Volkswagen Golf Plus, Toyota Prius+ and those have almost entirely disappeared (Golf Plus and Prius Plus aren't made anymore; Picasso will disappear this year, etc).
BMW series 5, Audi A6 etc are sedans. These are strongly declining too; SUVs make more about 40% of sales of new vehicles in Europe.
