It would be even better if the attendants did not omit information on which cars are actually available to be leased. They will not let you choose the model. For example, if you take the C category they will soon get you a Sandero. If you ask if you have the HB20 say no. When you go out there, the car is full of HB20 of category C. That does not seem to understand.
