Reminder to all travelers: Make sure to clarify all charges at the rental point. Don't assume it's j

We rented a Q3 and were told there was no Q5 available. We impulsively agreed, and the staff didn't mention how much extra it would cost, just handed us the invoice. Later we found out renting the car for the week cost 5000 RMB… Adding an extra driver required an additional fee, and they charged us just because we provided two licenses, assuming we were two drivers. Isn't that unreasonable? Returning the car an hour late incurs a significant fee. Is there a clear standard for these fees, or do they just charge an exorbitant amount for any delay? We won't use Europecar again. After returning and disputing it with the rental company, the results were minimal since we had already paid. It was tough to get anything back.
