Congratulations on your 75th anniversary

06/12/2026 Energies

Autohaus Hahn in Überlingen, a long-standing partner of Oest Energies, is celebrating a milestone in its history.

The trusting collaboration with our petrol station partners forms the basis for our shared success under the AVIA brand. We have been on this journey with many business partners for a very long time – with Autohaus Hahn for 74 years now. A success story that we celebrated together as part of the car dealership’s 75th anniversary with an entertaining programme and many guests.
