The Opel hostess at the recent Amsterdam Auto Show was overly enthusiast. She was young, dressed like you expect a hostess is dressed and regarded me as a possible Opel client. While all I was doing was admiring the colour scheme of the small Adam hipster, a 1970s combo of beige and brown. 'Do you like the car, sir?' she asked. 'I love the color,' I answered in true honesty. Her reply hit me like a bullet. 'Yes, a bit like your style, retro.'
