I've always thought of cup holders as a useless gimmick found in lesser cars and which Mercedes-Benz were above .
Having said that , some of my pre-airbag cars had circular indents in the lid of the glovebox when it was in the open position , as did the earlier vans such as the 208D or 508D etc . These were perfect for the odd can of juice .
Earlier today , I partook in a McDonalds take away meal ( I try not to do it more than about once a month ) and , as usual , stood the drinks carton in the rear corner of the year selector quadrant when parked up .
