Picked up the car at midnight, service was good. However, the oil light came on and they were out of spare oil, so we had to go to a gas station to add oil. Fortunately, we insisted that they come with us, and it took visits to two gas stations to find oil. Speaking English didn't work well in the German-speaking region. Schengen area at midnight, not easy.

Europcar, service was okay. No major issues, but QEEQ was disappointing, no words to describe.

The airport location is easy to find, but the city navigation for the drop-off location is a bit confusing. However, I eventually found it.

The store is right at Munich Airport T2 counter. It's easy to find following the signage after you get off the plane. The shop is right next to SIXT. The green logo is very eye-catching.

I am still waiting for my updated receipt, having had to take it for an extra day.
