It's like the pop open rear windows on Suburbans and Expeditions. It's an area Ford screwed up on my Flex. I wish the Flex had opening rear windows to help with air flow.Those 2 windows would provide a lot of ventilation and removable in less than 2 minutes as opposed to taking the roof completely off in perhaps 20 minutes. Then, what do you do if it rains? You won't have the top with you, but the windows would be stored in the vehicle.
