Every year the numbers of exhibitors and visitors increase – a sign that the Techno Classica in Essen has strong public appeal. Oldtimer fans from all over the world use this show as a communication platform, a business forum and a source of new trends. Motoring history lived on the Audi Tradition stand this year. From April 6 to 9, 2006, visitors saw an Auto Union Type C, a black Wanderer W 25 K, a Wanderer Streamline, a Horch 930 V and a Horch 930 S, an Audi 225 Cabrio in red and a Audi 5/30 Type P. On a special area devoted to the Gran Premio Nuvolari, Audi Tradition had an Auto Union Type D on display.
