1-2-3 Istanbul!

Katrin Bauerfeind and Henning Wehland embark on another road trip adventure, following "1-2-3 Moscow". This time, they journey through the Balkans to Istanbul in "1-2-3 Istanbul!". Along the way, they must work together and against each other to complete tasks and earn integration points. Traveling in a VW bus, they visit various stations, aiming to accumulate enough points to win the grand prize: the winner's trophy and a pass. The journey covers approximately 3000 kilometers.
