If a normal blacked-out Range Rover Sport isn't sneaky enough for you, consider the just-announced Stealth Pack.
Its main distinguishing feature is a matte dark grey finish for the entire body, which goes along with black trim all around and matching fit-and-finish inside the cabin. The SUV also arrives wrapped in a paint protection film.
Only the Dynamic SE version can be optioned with this package, but at least you can choose the powertrain.
