All they cared about was us upgrading the car for more money. When we said no, they immediately changed their attitude and became very dismissive.

Not entirely impolite, but the conversation was unpleasant. Diesel cars need to add AdBlue, which is uncommon in China. I didn't know about it, and they should have informed me when I picked up the car to avoid problems later on. I had to contact customer service multiple times, and international calls are expensive! Luckily, I saw the prompt. If I hadn't noticed it, who would have paid for the towing service? I later realized that this thing had to be added continuously. So why not mention it in advance? Tourists from other countries might not be familiar with your car's special requirements! I added AdBlue twice. When I claimed the reimbursement, the counter staff asked me why it was twice. How should I answer that? I could only say that your car prompted me twice! Such unnecessary questions are not needed. I didn't want to add it twice either! Additionally, when charging fees, just charge my credit card in euros. My credit card will handle the conversion. Why convert to dollars? Not only is the exchange rate high, but there are also extra fees!

Be warned, the rental company already charged for insurance through the booking platform, but at the store, they will add a super expensive insurance without asking, which is way more costly than the rental fee. This is a deceptive tactic. Additionally, the documents are mostly in Spanish, making it hard to understand. You might think you have fully paid, but that’s not the case. Do not fall for it!!! Do not fall for it!!! Do not fall for it!!!

The queue was very slow. The most crucial issue was that the right rear tire burst shortly after I started driving. Although I refueled to full, they claimed it wasn't full and charged me an extra 10 euros.

The staff were very thorough, double-checking all information. Very responsible.
