I chose a Mercedes E, but got a BMW 320i Touring instead. Slightly disappointed.

Out of nowhere, they requested some number, and even after calling the car rental customer service, they couldn't figure out what number it was. It took more than half an hour without providing any number before the rental was completed. I still don't understand the whole situation!

When booking, it was specified that we would travel to other countries, including Eastern Europe. Upon pickup, we were forced to buy additional insurance because the trip included Eastern Europe. This should have been clarified when placing the order. After over an hour of negotiation, we managed to reduce the extra insurance cost twice. In the end, we spent an additional 50 euros on insurance.

When we arrived in Frankfurt, the Mercedes 8-seater we reserved was unavailable, and they insisted on giving us a Ford 7-seater instead. We had eight people, how could we all fit? We went back to negotiate with the lady at the counter. She insisted that only the 7-seater was available. The two cars are of different sizes and not even in the same group. She was clearly lying, saying that the rest were all 9-seaters that required extra payment to upgrade. We argued that this was Hertz's problem and they needed to resolve it. She eventually said she would try to get a car from a nearby location but couldn't guarantee it. She asked us to wait on a nearby sofa, but we insisted on waiting at the counter. In less than a minute, she rummaged around and suddenly found the 8-seater Mercedes right next to the Ford. This is blatant lying. If not for the communication between Zuzuche and Hertz, I would have sent an email to complain. I have Hertz's gold card and this is the kind of deceptive service I get!

The service at the Frankfurt Airport branch in Germany was just average. When picking up the car, a hold was placed for a full tank of fuel. I booked a Benz C but received a Jaguar X20d diesel car instead. The car felt a bit small, especially the trunk, but the diesel engine did reduce travel costs. I was a bit late returning the car, having mistakenly entered the underground parking and returning it just over ten minutes late. I was charged an extra day because I picked up the car slightly early, despite confirming with the staff that I could wait until 9 AM to collect it. They agreed, but still charged according to the scheduled time. During the pickup, I noticed minor paint scratches and discussed them with the staff, so the actual pickup time was around 9:30 AM, but I didn't ask them to reprint the pickup contract. In the end, I had to negotiate with the manager at the branch, explaining the situation, and they ended up charging me a little under 15 Euros. Typical Germans, very rigid! While they weren't wrong and had a strong sense of contract, their service awareness was practically non-existent!
