I installed the Z4 first aide kit boxes under the seats a week ago. Now my sunglasses and driving gloves are easy to reach and out of sight when stored. The gloves are safer than they are in the door pocket, and the sunglasses are easier to reach than they are in the central storage compartment. Installation is described further down the board. It felt a little odd when working on the driverís seat to work with a tap left-handed and upside down, but it wasnít a problem. If you are in Northern Virginia, you can see them at the Blue Ridge Chapter of the BMWCCA wine tasting May 8.
