After his retreat in 1955 from active motorcycle racing he started to search for historical motorcycles throughout Europe. Some of these discoveries he kept to himself; having let them be restored, he exchanged and sold them. In 1967 he founded one of the first vintage motor clubs in Austria and for a short period he was president of the Austrian Vintage Club Association in 1976.
One of his great dreams became reality with the legendary "Oldtimer Grand Prix" on the Salzburgring in the years between 1974 and 1994, which took place nine times: 1974, 1975, 1976, 1978, 1979, 1981, 1983, 1985 and 1987. Stars like Niki Lauda, Juan Manuel Fangio and the above-mentioned motorcycle racers came to this event for vintage cars and motorcycles. Mercedes-Benz sent the famous "Silver Arrows", and more than 100 cars and up to 250 motorcycles joined this event each year.
