Well, it's very debatable what makes a car "special". That Prius is Esther Rantzen's own car so in this case it should be featured. And I wouldn't say a Prius is very common in Europe. Maybe among rich people who want to make a green statement.

Actually I think I have to see my first Prius in the flesh, although they are sold in Belgium. Plenty of Yaris in stead. (which are probably greener anyway)
