In our home country, we took the same car with the same people and luggage to the airport, but the staff here insisted that the Mercedes C-class couldn't fit our luggage and asked us to pay for an upgrade to an Audi A4 wagon. Coincidentally, another customer nearby was also asked to upgrade. It seems the reviews about forced upgrades are true. We were in a hurry, so we had to upgrade. Fortunately, the A4 was a diesel car, as I hoped, and had only 3277 kilometers, almost brand new. When returning the car, the staff inspected it very carefully, noticing a tiny chip on the windshield caused by a small stone. Thankfully, we had full insurance. I checked the windshields of a few nearby cars and saw many such tiny chips; the company considers them as damage. I suggest getting full insurance when renting a car. Overall, the car was fine, but after driving 1000 kilometers, it indicated that it needed one liter of oil, quite similar to domestic Audi cars needing oil for long trips.

I was two and a half hours late to pick up the car and was told the vehicle was no longer available. Communication with customer service was unhelpful (they said it was my fault for not reading the rental terms). I had to negotiate with the car rental company myself, and they finally resolved it (originally rented at Terminal 2, but they contacted Terminal 1 where a car was available).

We had read the reminders provided by Zuzuche before arriving at the Frankfurt store, but the staff informed us that the car we booked was unavailable and gave us a similar one, which actually had a much smaller trunk. They did not ask us if we needed GPS or any additional services though we declared that we didn't need any extras and had already paid through Zuzuche. When signing the agreement, the staff positioned the paper so it covered the upper part, which we couldn't see. After signing it, we found out about the additional charges only when returning the car. We have rented cars directly or through Zuzuche from various companies across Europe multiple times, but this was the first time we faced such an issue. It was also shocking that we couldn't communicate in English over their customer service phone line. We will definitely not choose Europcar again, as this was highly dishonest and felt like a scam! Zuzuche also refused to help us further because we had signed the agreement, which was very disappointing!

The rental company made a mistake with the terminal. I booked a Passat, but they gave me a Peugeot 3008 instead. It seems the Peugeot 3008 is cheaper. Fortunately, the car comes with a navigation system, which is quite convenient.

Very good car rental company.
