Uber Black? - Mexico City

I thought uber black was for a premium car?

We ordered Uber black 3x and twice a BYD make branded with “vemo” showed up. The most recent car (pics above) had clearly been in accidents. They also played ads in the car until I asked them to be turned off as we had requested a “quiet” ride.

How is this car considered luxury? What criteria does Uber use? The economy cars we rode in were nicer and half the price.
