Since most all cars have shipped without the parcel shelf which will be forthcoming I'm wondering what owners feel about not having it. Do you find you can live comfortably without the security the parcel shelf provides hiding items in the back? Are you inconvenienced by having to store items in the frunk you would normally put in back? Do you use a makeshift cover of some type to hide items in the back? Basically, do you think the parcel shelf is as necessary as when you ordered it and how strongly would you recommend it to people configuring their cars?
