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.

There was no problem with the queue time. The main issue during the service was the insurance. Before departure, I had purchased full insurance on the Zuzuche website, but when I arrived at the local rental counter, I was informed it wasn't full insurance and had to pay over a hundred euros more. As tourists driving in a foreign country, we definitely choose to buy insurance, so I don't understand what the difference is between Zuzuche's full insurance and the car rental company's full insurance.

After returning the car in Munich and boarding the train to Frankfurt, I realized that I hadn't returned the keys. I proactively called to ask if I should send them back via DHL from Frankfurt or return them to Europcar at Frankfurt Airport. After a while, the branch called back, insisting that I must come back immediately and take full responsibility for any consequences. I explained that I had an international flight connection and couldn't just jump off the train. They kept insisting that I return immediately or face huge fines.

Convenient

Unfortunately the vehicle that I originally booked was not available. I was offered a vehicle in the same class, but that was a matter of opinion, as I was unable to get all my bags in. After going all the way back to the desk to complain, I was offered a suitable vehicle that would fit my needs.
