They were comparing the cheapest and the most expensive car from the Fiat group: a Fiat 127 (similar to a Fiat 500 nowadays) against a Ferarri Testarossa. The first test was to get 3 people from Munich to Augsburg (approx. 70km), the Ferarri lost with about 30 minutes differencebecause it had to drive two times ;) Regards Thomas
