When we arrived at the counter to pick up the car, everything was prepared in advance. However, even though we had already prepaid for crossing the Czech border when renting, we were told at pick-up that it was not allowed. Alternatively, we could switch to a Toyota 7-seater, but we were not notified about this beforehand.

Previous rental did not include insurance. The Avis staff added insurance without informing us. Be cautious of this pitfall when renting a car.

1. The breakdown and origins of each fee were unclear. I never received the contract after picking up the car. They said they'd email it in 3-4 hours, but I never got it. The detailed invoice was only provided when returning the car, and it wasn't clear enough; 2. We booked a Volkswagen, but they gave us a CUPRA at the same price, despite having reserved the Volkswagen well in advance and arriving on time. The car rental company switched our car under various pretexts, which was unreasonable and resulted in extra costs; 4. On the return day, the car was fully refueled and had no issues, yet the invoice included a full tank refueling charge... 5. We only agreed to the full insurance, an additional driver fee, and the cross-border fee for driving out of Germany. No other charges should have been applied. Besides the 5200 RMB for the rental, my credit card was overcharged by an additional 8000 RMB, with excessive extra fees.

They switched to a smaller car, which is highly irresponsible!

The car was fine, but the German lady at the rental office was extremely grumpy. Just arriving in a foreign country and not yet accustomed to the English environment, I was slow to respond, and she was incredibly impatient. She misread my order and I had to argue with her for over half an hour until another employee came and sorted out my order. Due to the additional half-hour, I was charged for an extra day of rental. I asked for a refund through the rental platform, and also disputed the charge with my credit card company. When neither route seemed to work, the rental company proactively refunded me for the extra day. Lifelong fan of this rental platform.
