"Oh Lord, she is a little girl!" was a phrase often heard at one such event a few years back. It was the day on which Theresa Unnold was able to accompany her grandparents for the very first time as part of the Bertha Benz Challenge. At the time only 10 years of age, she avidly took in all of the new impressions: the vast numbers of unknown faces, the unusual vehicles, the smell of petrol which she so loved. The most interesting aspect, however, remained the sequence of events. Her grandmother promised her: "As soon as you get your driving licence, we'll form a women's team and drive the route together." From that day on, Theresa never missed a Bertha Benz Challenge. "And this year, my time had come," said the smiling 17-year-old who has only just received her driving licence. At the 125th anniversary of this legendary and pioneering journey, Theresa Unnold sat behind the steering wheel of the "Stuttgart", a Mercedes-Benz 8/38 hp from 1928.
