My dealer mentioned this survey to me at my delivery today. He said VW dont send them out to every new VW owner and he was instructed to inform people of this fact. He said there is some psychology behind it that if everyone thinks they get a survey, they are less likely to fill it in as they think the next person will bother. Apparently, if people feel they are "selected" to complete the survey and not just sent one automatically they are more inclined to complete it and complete it more accurately? - I suppose that makes abit of sense!
