I'm not sure about the other clues yet, but "Ich bereue nichts" is German for "Je ne regrette rien", probably the most famous song performed by Girl F, Édith Piaf.
Her stage name came from a nickname she was given when she was younger, "piaf" being a dialectical word meaning sparrow, or a small bird in general. So to follow the logic, we need a German sparrow. I've just been looking up my Langenscheidt, and one German word for sparrow is "Spatz", which links to Dashboard 12. Originally designed by Egon Brütsch, the Spatz was made under licence and modified by Harald Friedrich of Altzmetall, marketed by Bayerishe Autowerke GmbH, formed in conjunction with the Victoria motorcycle company, and was later sold as the Victoria 250.
