Of course you see a theme. These are mass produced transport boxes and they have to appeal to mass fashion. Hence the colour, hence the shape. Euroboxes.
Saw a cluster of then down our road yesterday. In this case all variants on the Range Rover theme, all in black of course and with tinted windows. I believe a couple were BMW but you would have had to look at the label to be sure.
What surprises me is that, apart from the operating costs and reliability, anyone cares whether the brand is VW ( ie audi, seat, skoda) or renault ( ie Nissan, Mitsubishi) or the various Panzers from Merc and BM.
The days when you had a choice, like the days when the roads were free, are gone.
