Natacha Le Jeune lives in Paris. She has recorded three albums with her bands so far and regularly performs as a DJ in nightclubs. When she’s on tour, she clocks up as many as 75,000 kilometers (47,000 miles) a year in her tour bus. Jim Gabaret also lives in the capital, where he teaches philosophy at the Sorbonne. Last year he made some documentary films as well and wrote his first novel, which is due to be published in 2017. We invited the two of them to try out the C-Class – not in Paris, but in the city of Nantes in Western France, with its mix of traditional houses and modern architecture. Even before the start of the test drive, it was clear that they had quite different approaches to travelling by car. While Jim was content to ride shotgun, Natacha wanted to take the wheel. Each of them had good reasons for their choice, which they told us about as the day went on.
