Argentina's major production-car race, known as "the toughest of them all," did not seem tough enough for the two blonde flashes from Sweden, Ewy Rosqvist and Ursula Wirth. Entering as rookie drivers for the Mercedes-Benz team, they soon found themselves alone—the other four team cars had exited long before the halfway mark. However, "Rennleiter" Karl Kling had good reason to be confident that the 220-SEb could handle the challenge, and the girls possessed stamina, discipline, and a very heavy foot, in addition to their good looks.

They not only successfully upheld the prestige of Mercedes-Benz but also achieved numerous unprecedented feats. Winning every leg of the Gran Premio simply "couldn't be done"; yet they did it and rewrote the record books. Their 220-SEb was undoubtedly the fastest car, but there are few portions of the Gran Premio where speed alone counts; it is a test of both the driver and the machinery.

Many of its sections minimize differences in mechanical power and demand physical endurance and extraordinary driving skills. The girls had everything that was needed. Passing 250 cars at night on a wet road and driving at the edge of a precipice on a twisty, treacherous, narrow, and slippery gravel road are challenges we used to call "man-sized jobs," and there is plenty of this in the standard of the Gran Premio.

I'm empty in my head. The light is becoming too bright, and I find it irritating. I let down the shutters completely and lie down on the bed. Street noise can be heard all the way up, a humming of voices, laughter, horns, and wheel squeaks when someone brakes. I get up and shut the window entirely. I can’t hear the creaking anymore. I feel pathetic. Suddenly, I remember my mother's words when I began rallying: - Why are you interested in that? she asked uncomprehendingly. Think if you run into something unexpected in Argentina that might expose Ursula to danger. What would our mothers say if anything happened to us? I still can’t cry. Yet I know that it would help me release the horrid cramp in my neck. What a ridiculous idea to participate in rallying! What has driven me to it? Why haven’t I stayed home, by the pots that many reporters have asked about?

When I close my eyes, the hotel room disappears, and I see my home in front of me. But Sweden is far, far away—one third of the circumference of the Earth away. At home, it's late in the evening while the sun shines here. When I think of our farm, I feel the clear, fresh air that always blows from the Baltic Sea. What has led me to choose this extreme profession, that has brought me this far to Argentina? I open my eyes and stare up at the white ceiling. This is "examination time," when I have to decide if I should continue with this profession or give up."
