The Worthersee Treffen is one of the more unique auto events on the calendar. It’s far from a traditional auto show, but it’s been home to some pretty incredible debuts over the past few years. Remember, this is the same event where companies like Audi and Volkswagen make yearly concept debuts. VW, in particular, holds Worthersee in high esteem because, in addition to debuting models at the event, it uses the venue to introduce apprentice-built concepts of the Golf GTI the Volkswagen Vocational Training program. This year, 13 apprentices are headed to Worthersee to unveil the newest one-off model of this unique lineage: the Volkswagen Golf GTI First Decade.
