The Jeep Grand Cherokee cannot be driven on dusty roads, therefore as an "off-road 4WD" it doesn't suit what we bought it for. We do not drive it with the windows open.
We are now selling it. It's a disgrace that they are still being advertised as an off-road 4wd, don't know of many "off-roads" that are bitumen.
We cannot hang clothing in the back seat unless it's covered in plastic.
