Car auction market in naseem (khurais road to dammam)

Is there someone who has experience in visiting the car auction market in naseem? It is a place where individuals come to sell their cars and is mostly sold by jemeni intermediaries.  I was there and it seems that cars are being sold very cheaply. Any advice or tips on this because everything looks really like a bargain. And some of the cars or still quite new if you look at odo and exterior.

Did someone buy there before? Please share your experiences.

No one.?
