I’d have speculated (since I am not in the market for these products myself) that selling luxury cars would involve presenting them in a special way and giving the purchase a sense of occasion.
In contrast, this dealership in Riyadh has luxury cars piled up like tins of tomatoes.
Perhaps the local clientele prefer seeing as much choice as possible and value that over lots of space being dedicated to any individual model.
You get the impression from the selection featured that they’d like to see as much variety as possible in terms of models and shapes and sizes.
