You know I myself am kinda down on pointless ostentatious expenditure and all, but think about it. Everybody knows that in that part of the world they've got some serious potent solar flux pretty much year round. Your ordinary cars absorb it all as heat, whereupon the engine wastes fuel and emits nasty effluents powering the overstressed a/c compressor. But this car? When the ruthless desert Sun hurls light and heat upon it, it flings them back in the Sun's face.
